[media] media: vb2: Fix regression on poll() for RW mode

2016-04-25T13:21:23Z

When using a device is read/write mode, vb2 does not handle properly the first select/poll operation. The reason for this, is that when this code has been refactored, some of the operations have changed their order, and now fileio emulator is not started. The reintroduced check to the core is enabled by a quirk flag, that avoids this check by other subsystems like DVB.

[media] videobuf2-core: Check user space planes array in dqbuf

2016-04-13T19:19:05Z

The number of planes in videobuf2 is specific to a buffer. In order to verify that the planes array provided by the user is long enough, a new vb2_buf_op is required. Call __verify_planes_array() when the dequeued buffer is known. Return an error to the caller if there was one, otherwise remove the buffer from the done list.

Pull ARM updates from Russell King: "Another mixture of changes this time around: - Split XIP linker file from main linker file to make it more maintainable, and various XIP fixes, and clean up a resulting macro. - Decompressor cleanups from Masahiro Yamada - Avoid printing an error for a missing L2 cache - Remove some duplicated symbols in System.map, and move vectors/stubs back into kernel VMA - Various low priority fixes from Arnd - Updates to allow bus match functions to return negative errno values, touching some drivers and the driver core. Greg has acked these changes. - Virtualisation platform udpates form Jean-Philippe Brucker. - Security enhancements from Kees Cook - Rework some Kconfig dependencies and move PSCI idle management code out of arch/arm into drivers/firmware/psci.c - ARM DMA mapping updates, touching media, acked by Mauro. - Fix places in ARM code which should be using virt_to_idmap() so that Keystone2 can work. - Fix Marvell Tauros2 to work again with non-DT boots. - Provide a delay timer for ARM Orion platforms" * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (45 commits) ARM: 8546/1: dma-mapping: refactor to fix coherent+cma+gfp=0 ARM: 8547/1: dma-mapping: store buffer information ARM: 8543/1: decompressor: rename suffix_y to compress-y ARM: 8542/1: decompressor: merge piggy.*.S and simplify Makefile ARM: 8541/1: decompressor: drop redundant FORCE in Makefile ARM: 8540/1: decompressor: use clean-files instead of extra-y to clean files ARM: 8539/1: decompressor: drop more unneeded assignments to "targets" ARM: 8538/1: decompressor: drop unneeded assignments to "targets" ARM: 8532/1: uncompress: mark putc as inline ARM: 8531/1: turn init_new_context into an inline function ARM: 8530/1: remove VIRT_TO_BUS ARM: 8537/1: drop unused DEBUG_RODATA from XIP_KERNEL ARM: 8536/1: mm: hide __start_rodata_section_aligned for non-debug builds ARM: 8535/1: mm: DEBUG_RODATA makes no sense with XIP_KERNEL ARM: 8534/1: virt: fix hyp-stub build for pre-ARMv7 CPUs ARM: make the physical-relative calculation more obvious ARM: 8512/1: proc-v7.S: Adjust stack address when XIP_KERNEL ARM: 8411/1: Add default SPARSEMEM settings ARM: 8503/1: clk_register_clkdev: remove format string interface ARM: 8529/1: remove 'i' and 'zi' targets ...

[media] v4l: Add generic pipeline power management code

2016-03-03T15:29:25Z

When the Media controller framework was merged, it was decided not to add pipeline power management code for it was not seen generic. As a result, a number of drivers have copied the same piece of code, with same bugfixes done to them at different points of time (or not at all). Add these functions to V4L2. Their use is optional for drivers. [mchehab@osg.samsung.com: Fix merge conflicts] Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab
