2017-03-16parport: fix attempt to write duplicate procfilesSudip Mukherjee1-2/+4
Usually every parallel port will have a single pardev registered with it. But ppdev driver is an exception. This userspace parallel port driver allows to create multiple parrallel port devices for a single parallel port. And as a result we were having a nice warning like: "sysctl table check failed: /dev/parport/parport0/devices/ppdev0/timeslice Sysctl already exists" Use the same logic as used in parport_register_device() and register the proc files only once for each parallel port.

2017-02-27lib/vsprintf.c: remove %Z supportAlexey Dobriyan1-1/+1
Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.

2014-11-26parport: parport_pc, do not remove parent devices earlyJiri Slaby1-3/+4
When the parport_pc module is removed from the system, all parport devices are iterated in parport_pc_exit and removed by a call to parport_pc_unregister_port. Note that some parport devices have its 'struct device' parent, known as port->dev. And when port->dev is a platform device, it is destroyed in parport_pc_exit too. Now, when parport_pc_unregister_port is called for a going port, drv->detach(port) is called for every parport driver in the system. ppdev can be one of them. ppdev's detach() tears down its per-port sysfs directory, which established port->dev as a parent earlier. But since parport_pc_exit kills port->dev parents before unregisters ports proper, ppdev's sysfs directory has no living parent anymore. This results in the following warning: WARNING: CPU: 1 PID: 785 at fs/sysfs/group.c:219 sysfs_remove_group+0x9b/0xa0 sysfs group ffffffff81c69e20 not found for kobject 'parport1' Modules linked in: parport_pc(E-) ppdev(E) [last unloaded: ppdev] CPU: 1 PID: 785 Comm: rmmod Tainted: G W E 3.18.0-rc5-next-20141120+ #824 ...

So switch the order of killing the two structures. But since port is freed by parport_pc_unregister_port, we have to remember port->dev in a local variable. Perhaps nothing worse than the warning happens thanks to the device refcounting. We *should* be on the safe side.

2013-12-10parport: parport_pc: remove double PCI ID for NetMosSebastian Andrzej Siewior1-8/+2
In commit 85747f ("PATCH] parport: add NetMOS 9805 support") Max added the PCI ID for NetMOS 9805 based on a Debian bug report from 2k4 which was at the v2.4.26 time frame. The patch made into 2.6.14. Shortly before that patch akpm merged commit 296d3c783b ("[PATCH] Support NetMOS based PCI cards providing serial and parallel ports") which made into v2.6.9-rc1. Now we have two different entries for the same PCI id. I have here the NetMos 9805 which claims to support SPP/EPP/ECP mode. This patch takes Max's entry for titan_1284p1 (base != -1 specifies the ioport for ECP mode) and replaces akpm's entry for netmos_9805 which specified -1 (=none). Both share the same PCI-ID (my card has subsystem 0x1000 / 0x0020 so it should match PCI_ANY). While here I also drop the entry for titan_1284p2 which is the same as netmos_9815.

2013-12-10parport_pc: remove unnecessary pci_set_drvdata()Jingoo Han1-2/+0
The driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-12-10parport: parport_pc: fix id print of a deviceSebastian Andrzej Siewior1-6/+2
Since commit 7106b4e3 ("8250: Oxford Semiconductor Devices") the debug print of the device id does no longer match the real device if it is located in the "enum" behind oxsemi_pcie_pport. The reason is that the code assumes that each id contains one entry in the PCI table. The fix is to lookup the currently used id from the id-> parameter.

2013-11-26zorro: ZTWO_VADDR() should return "void __iomem *"Geert Uytterhoeven1-1/+1
ZTWO_VADDR() converts from physical to virtual I/O addresses, so it should return "void __iomem *" instead of "unsigned long". This allows to drop several casts, but requires adding a few casts to accomodate legacy driver frameworks that store "unsigned long" I/O addresses.

2013-11-14Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-armLinus Torvalds1-2/+6
Pull DMA mask updates from Russell King: "This series cleans up the handling of DMA masks in a lot of drivers, fixing some bugs as we go. Some of the more serious errors include: - drivers which only set their coherent DMA mask if the attempt to set the streaming mask fails. - drivers which test for a NULL dma mask pointer, and then set the dma mask pointer to a location in their module .data section - which will cause problems if the module is reloaded. To counter these, I have introduced two helper functions: - dma_set_mask_and_coherent() takes care of setting both the streaming and coherent masks at the same time, with the correct error handling as specified by the API. - dma_coerce_mask_and_coherent() which resolves the problem of drivers forcefully setting DMA masks. This is more a marker for future work to further clean these locations up - the code which creates the devices really should be initialising these, but to fix that in one go along with this change could potentially be very disruptive. The last thing this series does is prise away some of Linux's addition to "DMA addresses are physical addresses and RAM always starts at zero". We have ARM LPAE systems where all system memory is above 4GB physical, hence having DMA masks interpreted by (eg) the block layers as describing physical addresses in the range 0..DMAMASK fails on these platforms. Santosh Shilimkar addresses this in this series; the patches were copied to the appropriate people multiple times but were ignored. Fixing this also gets rid of some ARM weirdness in the setup of the max*pfn variables, and brings ARM into line with every other Linux architecture as far as those go" * 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm: (52 commits) ARM: 7805/1: mm: change max*pfn to include the physical offset of memory ARM: 7797/1: mmc: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7796/1: scsi: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7795/1: mm: dma-mapping: Add dma_max_pfn(dev) helper function ARM: 7794/1: block: Rename parameter dma_mask to max_addr for blk_queue_bounce_limit() ARM: DMA-API: better handing of DMA masks for coherent allocations ARM: 7857/1: dma: imx-sdma: setup dma mask DMA-API: firmware/google/gsmi.c: avoid direct access to DMA masks DMA-API: dcdbas: update DMA mask handing DMA-API: dma: edma.c: no need to explicitly initialize DMA masks DMA-API: usb: musb: use platform_device_register_full() to avoid directly messing with dma masks DMA-API: crypto: remove last references to 'static struct device *dev' DMA-API: crypto: fix ixp4xx crypto platform device support DMA-API: others: use dma_set_coherent_mask() DMA-API: staging: use dma_set_coherent_mask() DMA-API: usb: use new dma_coerce_mask_and_coherent() DMA-API: usb: use dma_set_coherent_mask() DMA-API: parport: parport_pc.c: use dma_coerce_mask_and_coherent() DMA-API: net: octeon: use dma_coerce_mask_and_coherent() DMA-API: net: nxp/lpc_eth: use dma_coerce_mask_and_coherent() ...

2013-10-23Kconfig cleanup (PARPORT_PC dependencies)Mark Salter1-3/+7
Remove messy dependencies from PARPORT_PC by having it depend on one Kconfig symbol (ARCH_MIGHT_HAVE_PC_PARPORT) and having architectures which need it, select ARCH_MIGHT_HAVE_PC_PARPORT in arch/*/Kconfig. New architectures are unlikely to need PARPORT_PC, so this avoids having an ever growing list of architectures to exclude. Those architectures which do select ARCH_MIGHT_HAVE_PC_PARPORT in this patch are the ones which have an asm/parport.h (or use the generic version).
