2022-06-20fbcon: Fix boundary checks for fbcon=vc:n1-n2 parametersHelge Deller1-3/+5
The user may use the fbcon=vc:<n1>-<n2> option to tell fbcon to take over the given range (n1...n2) of consoles. The value for n1 and n2 needs to be a positive number and up to (MAX_NR_CONSOLES - 1). The given values were not fully checked against those boundaries yet. To fix the issue, convert first_fb_vc and last_fb_vc to unsigned integers and check them against the upper boundary, and make sure that first_fb_vc is smaller than last_fb_vc.

2022-06-20fbcon: Fix accelerated fbdev scrolling while logo is still shownHelge Deller1-4/+0
There is no need to directly skip over to the SCROLL_REDRAW case while the logo is still shown. When using DRM, this change has no effect because the code will reach the SCROLL_REDRAW case immediately anyway. But if you run an accelerated fbdev driver and have FRAMEBUFFER_CONSOLE_LEGACY_ACCELERATION enabled, console scrolling is slowed down by factors so that it feels as if you use a 9600 baud terminal. So, drop those unnecessary checks and speed up fbdev console acceleration during bootup.

2022-06-15drm/bridge: anx7625: Zero error variable when panel bridge not presentNícolas F. R. A. Prado1-1/+3
While parsing the DT, the anx7625 driver checks for the presence of a panel bridge on endpoint 1. If it is missing, pdata->panel_bridge stores the error pointer and the function returns successfully without first cleaning that variable. This is an issue since other functions later check for the presence of a panel bridge by testing the trueness of that variable. In order to ensure proper behavior, zero out pdata->panel_bridge before returning when no panel bridge is found.

2022-06-13Revert "fbdev: vesafb: Allow to be built if COMPILE_TEST is enabled"Javier Martinez Canillas1-1/+1
This reverts commit fa0e256450f27a7d85f65c63f05e6897954a1d53. The kernel test robot reported that attempting to build the vesafb driver fails on some architectures, because these don't define a `struct screen_info`. This leads to linking errors, for example on parisc with allyesconfig: hppa-linux-ld: drivers/video/fbdev/vesafb.o: in function `vesafb_probe': >> (.text+0x738): undefined reference to `screen_info' >> hppa-linux-ld: (.text+0x73c): undefined reference to `screen_info' hppa-linux-ld: drivers/firmware/sysfb.o: in function `sysfb_init': >> (.init.text+0x28): undefined reference to `screen_info' >> hppa-linux-ld: (.init.text+0x30): undefined reference to `screen_info' hppa-linux-ld: (.init.text+0x78): undefined reference to `screen_info' The goal of commit fa0e256450f2 ("fbdev: vesafb: Allow to be built if COMPILE_TEST is enabled") was to have more build coverage for the driver but it wrongly assumed that all architectures would define a screen_info.

2022-06-13drm/edid: fix CTA data block collection size for CTA version 3Jani Nikula1-2/+0
The CTA Data Block Collection is valid only for CTA extension version 3. In versions 1 and 2, it is a reserved block, which we ignore. The DTD start offset (byte 2, or d in CTA-861 spec), which determines the CTA Data Block Collection size, is specified slightly differently for different versions: Version 1: d = offset for the byte following the reserved data block. If no data is provided in the reserved data block, then d=4. If no DTDs are provided, then d=0 Version 2: d = offset for the byte following the reserved data block. If no data is provided in the reserved data block, then d=4. If d=0, then no detailed timing descriptors are provided, and no data is provided in the reserved data block. Version 3: d = offset for the byte following the data block collection. If no data is provided in the data block collection, then d=4. If d=0, then no detailed timing descriptors are provided, and no data is provided in the data block collection. Ever since commit 9e50b9d55e9c ("drm: edid: Add some bounds checking"), we've interpreted 0 to mean there are no DTDs but it's all Data Blocks. Per the spec, Data Blocks are only valid for version 3, where we should interpret 0 to mean there are no data blocks. Follow the spec (and hope the EDIDs follow it too).

git://git.kernel.org/pub/scm/linux/kernel/git/crng/random Pull random number generator fixes from Jason Donenfeld: - A fix for a 5.19 regression for a case in which early device tree initializes the RNG, which flips a static branch. On most plaforms, jump labels aren't initialized until much later, so this caused splats. On a few mailing list threads, we cooked up easy fixes for arm64, arm32, and risc-v. But then things looked slightly more involved for xtensa, powerpc, arc, and mips. And at that point, when we're patching 7 architectures in a place before the console is even available, it seems like the cost/risk just wasn't worth it. So random.c works around it now by checking the already exported `static_key_initialized` boolean, as though somebody already ran into this issue in the past. I'm not super jazzed about that; it'd be prettier to not have to complicate downstream code. But I suppose it's practical. - A few small code nits and adding a missing __init annotation. - A change to the default config values to use the cpu and bootloader's seeds for initializing the RNG earlier. This brings them into line with what all the distros do (Fedora/RHEL, Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void... at least), and moreover will now give us test coverage in various test beds that might have caught the above device tree bug earlier. - A change to WireGuard CI's configuration to increase test coverage around the RNG. - A documentation comment fix to unrelated maintainerless CRC code that I was asked to take, I guess because it has to do with polynomials (which the RNG thankfully no longer uses). * tag 'random-5.19-rc2-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: wireguard: selftests: use maximum cpu features and allow rng seeding random: remove rng_has_arch_random() random: credit cpu and bootloader seeds by default random: do not use jump labels before they are initialized random: account for arch randomness in bits random: mark bootloader randomness code as __init random: avoid checking crng_ready() twice in random_init() crc-itu-t: fix typo in CRC ITU-T polynomial comment

The DSI lane count can be accessed via the dsi device pointer, make use of that. The DSI host pointer is only used in sn65dsi83_host_attach(), move the code around so that the host does not have to be cached in the driver private data. This simplifies the code further. No functional change. This has the added bonus that lt9211, tc358767, sn65dsi83 now use very similar *_mipi_dsi_host_attach() which is ripe for deduplication.

2022-06-12platform/x86: hp-wmi: Resolve WMI query failures on some devicesJorge Lopez1-2/+4
WMI queries fail on some devices where the ACPI method HWMC unconditionally attempts to create Fields beyond the buffer if the buffer is too small, this breaks essential features such as power profiles: CreateByteField (Arg1, 0x10, D008) CreateByteField (Arg1, 0x11, D009) CreateByteField (Arg1, 0x12, D010) CreateDWordField (Arg1, 0x10, D032) CreateField (Arg1, 0x80, 0x0400, D128) In cases where args->data had zero length, ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D008] at bit offset/length 128/8 exceeds size of target Buffer (128 bits) (20211217/dsopcode-198) was obtained. ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D009] at bit offset/length 136/8 exceeds size of target Buffer (136bits) (20211217/dsopcode-198) The original code created a buffer size of 128 bytes regardless if the WMI call required a smaller buffer or not. This particular behavior occurs in older BIOS and reproduced in OMEN laptops. Newer BIOS handles buffer sizes properly and meets the latest specification requirements. This is the reason why testing with a dynamically allocated buffer did not uncover any failures with the test systems at hand. This patch was tested on several OMEN, Elite, and Zbooks. It was confirmed the patch resolves HPWMI_FAN GET/SET calls in an OMEN Laptop 15-ek0xxx. No problems were reported when testing on several Elite and Zbooks notebooks.
