[media] drivers/media/media-devnode: clear private_data before put_device()

2016-05-07T14:43:53Z

Callbacks invoked from put_device() may free the struct media_devnode pointer, so any cleanup needs to be done before put_device(). Signed-off-by: Max Kellermann Signed-off-by: Mauro Carvalho Chehab

[media] media-devnode: add missing mutex lock in error handler

2016-04-06T12:39:56Z

We should protect the device unregister patch too, at the error condition. Signed-off-by: Max Kellermann Signed-off-by: Mauro Carvalho Chehab

[media] media: Fix media_open() to clear filp->private_data in error leg

Fix media_open() to clear filp->private_data when file open fails. Signed-off-by: Shuah Khan Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] media-devnode: move kernel-doc documentation to the header

2016-01-11T14:19:13Z

As we're using the headers file only for documentation, move the two kernel-doc macros to the header, and fix it to avoid warnings. Signed-off-by: Mauro Carvalho Chehab

[media] media-devnode: just return 0 instead of using a var

2014-09-03T20:59:28Z

Instead of allocating a var to store 0 and just return it, change the code to return 0 directly. Signed-off-by: Mauro Carvalho Chehab

[media] media: Use a better owner for the media device

2014-05-13T16:39:00Z

mdev->fops->owner is actually the owner of the very same module which implements media_device_register(), so it can't be unloaded anyway. Instead, use THIS_MODULE through a macro as does video_register_device(). Signed-off-by: Sakari Ailus Acked-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] media: Add 64--32 bit compat ioctl handler

Pull "Disintegrate and delete asm/system.h" from David Howells: "Here are a bunch of patches to disintegrate asm/system.h into a set of separate bits to relieve the problem of circular inclusion dependencies. I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that. We'll find out anything that got broken and fix it.. * tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system: (38 commits) Delete all instances of asm/system.h Remove all #inclusions of asm/system.h Add #includes needed to permit the removal of asm/system.h Move all declarations of free_initmem() to linux/mm.h Disintegrate asm/system.h for OpenRISC Split arch_align_stack() out from asm-generic/system.h Split the switch_to() wrapper out of asm-generic/system.h Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h Create asm-generic/barrier.h Make asm-generic/cmpxchg.h #include asm-generic/cmpxchg-local.h Disintegrate asm/system.h for Xtensa Disintegrate asm/system.h for Unicore32 [based on ver #3, changed by gxt] Disintegrate asm/system.h for Tile Disintegrate asm/system.h for Sparc Disintegrate asm/system.h for SH Disintegrate asm/system.h for Score Disintegrate asm/system.h for S390 Disintegrate asm/system.h for PowerPC Disintegrate asm/system.h for PA-RISC Disintegrate asm/system.h for MN10300 ...
