Remove obsolete bundled tfp410 driver with its "ti,tilcdc,tfp410" devicetree binding. No platform has ever used this driver in the mainline kernel and if anybody connects tfp410 to tilcdc he or she should use the generic drm tfp410 bridge driver.

Pull rdma fixes from Doug Ledford: "A small collection of -rc fixes. Mostly. One API addition, but that's because we wanted to use it in a fix. There's also a bug fix that is going to render the 5.5 kernel's soft-RoCE driver incompatible with all soft-RoCE versions prior, but it's required to actually implement the protocol according to the RoCE spec and required in order for the soft-RoCE driver to be able to successfully work with actual RoCE hardware. Summary: - Update Steve Wise info - Fix for soft-RoCE crc calculations (will break back compatibility, but only with the soft-RoCE driver, which has had this bug since it was introduced and it is an on-the-wire bug, but will make soft-RoCE fully compatible with real RoCE hardware) - cma init fixup - counters oops fix - fix for mlx4 init/teardown sequence - fix for mkx5 steering rules - introduce a cleanup API, which isn't a fix, but we want to use it in the next fix - fix for mlx5 memory management that uses API in previous patch" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: IB/mlx5: Fix device memory flows IB/core: Introduce rdma_user_mmap_entry_insert_range() API IB/mlx5: Fix steering rule of drop and count IB/mlx4: Follow mirror sequence of device add during device removal RDMA/counter: Prevent auto-binding a QP which are not tracked with res rxe: correctly calculate iCRC for unaligned payloads Update mailmap info for Steve Wise RDMA/cma: add missed unregister_pernet_subsys in init failure

git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux Pull ksys_mount() and ksys_dup() removal from Dominik Brodowski: "This small series replaces all in-kernel calls to the userspace-focused ksys_mount() and ksys_dup() with calls to kernel-centric functions: For each replacement of ksys_mount() with do_mount(), one needs to verify that the first and third parameter (char *dev_name, char *type) are strings allocated in kernelspace and that the fifth parameter (void *data) is either NULL or refers to a full page (only occurence in init/do_mounts.c::do_mount_root()). The second and fourth parameters (char *dir_name, unsigned long flags) are passed by ksys_mount() to do_mount() unchanged, and therefore do not require particular care. Moreover, instead of pretending to be userspace, the opening of /dev/console as stdin/stdout/stderr can be implemented using in-kernel functions as well. Thereby, ksys_dup() can be removed for good" [ This doesn't get rid of the special "kernel init runs with KERNEL_DS" case, but it at least removes _some_ of the users of "treat kernel pointers as user pointers for our magical init sequence". One day we'll hopefully be rid of it all, and can initialize our init_thread addr_limit to USER_DS. - Linus ] * 'remove-ksys-mount-dup' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux: fs: remove ksys_dup() init: unify opening /dev/console as stdin/stdout/stderr init: use do_mount() instead of ksys_mount() initrd: use do_mount() instead of ksys_mount() devtmpfs: use do_mount() instead of ksys_mount()

2019-12-14drm/gma500: Pass GPIO for Intel MID using descriptorsLinus Walleij3-74/+51
The GMA500 driver is using the legacy GPIO API to fetch three optional display control GPIO lines from the SFI description used by the Medfield platform. Switch this over to use GPIO descriptors and delete the custom platform data. We create three new static locals in the tc35876x bridge code but it is hardly any worse than the I2C client static local already there: I tried first to move it to the DRM driver state container but there are workarounds for probe order in the code so I just stayed off it, as the result is unpredictable. People wanting to do a more throrugh and proper cleanup of the GMA500 driver can work on top of this, I can't solve much more since I don't have access to the hardware, I can only attempt to tidy up my GPIO corner.

2019-12-13xen-blkback: prevent premature module unloadPaul Durrant1-0/+10
Objects allocated by xen_blkif_alloc come from the 'blkif_cache' kmem cache. This cache is destoyed when xen-blkif is unloaded so it is necessary to wait for the deferred free routine used for such objects to complete. This necessity was missed in commit 14855954f636 "xen-blkback: allow module to be cleanly unloaded". This patch fixes the problem by taking/releasing extra module references in xen_blkif_alloc/free() respectively.

2019-12-13CIFS: Close cached root handle only if it has a leasePavel Shilovsky5-4/+25
SMB2_tdis() checks if a root handle is valid in order to decide whether it needs to close the handle or not. However if another thread has reference for the handle, it may end up with putting the reference twice. The extra reference that we want to put during the tree disconnect is the reference that has a directory lease. So, track the fact that we have a directory lease and close the handle only in that case.
