When the driver calls cx88_risc_buffer() to prepare the buffer, the function call may fail, resulting in a empty buffer and null-ptr-deref later in buffer_queue(). The following log can reveal it: [ 41.822762] general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] PREEMPT SMP KASAN PTI [ 41.824488] KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007] [ 41.828027] RIP: 0010:buffer_queue+0xc2/0x500 [ 41.836311] Call Trace: [ 41.836945] __enqueue_in_driver+0x141/0x360 [ 41.837262] vb2_start_streaming+0x62/0x4a0 [ 41.838216] vb2_core_streamon+0x1da/0x2c0 [ 41.838516] __vb2_init_fileio+0x981/0xbc0 [ 41.839141] __vb2_perform_fileio+0xbf9/0x1120 [ 41.840072] vb2_fop_read+0x20e/0x400 [ 41.840346] v4l2_read+0x215/0x290 [ 41.840603] vfs_read+0x162/0x4c0 Fix this by checking the return value of cx88_risc_buffer() [hverkuil: fix coding style issues] Signed-off-by:

In fimc_is_register_subdevs(), we need to call of_node_put() for the reference 'i2c_bus' when breaking out of the for_each_compatible_node() which has increased the refcount. Fixes: 9a761e43 ("[media] exynos4-is: Add Exynos4x12 FIMC-IS driver") Signed-off-by:

Deprecate the hexium_gemini, hexium_orion, mxb and ttpci saa7146-based drivers: these drivers do not use the vb2 framework for video streaming, instead it uses the old videobuf framework. We want to get rid of these old drivers, so deprecated these for future removal. [hverkuil: update MAINTAINERS file] Signed-off-by:

Deprecate the dm644x_ccdc, dm355_cddc and dm365_isif davinci drivers: all three depend on the vpfe_capture driver, and that driver does not use the vb2 framework for video streaming, instead it uses the old videobuf framework. We want to get rid of these old drivers, so deprecated these for future removal. Note that include/media/davinci/vpfe_capture.h can't be moved to staging since it is used in arch/arm/mach-davinci/davinci.h. Signed-off-by:

The term 'videobuf' typically refers to the old videobuf version 1 framework. Avoid using this word in drivers that are converted to vb2. Signed-off-by:

Rename 'videobuf' to 'vb2' in the comment. This avoids confusing terminology since 'videobuf' typically refers to the old vb1 framework. Signed-off-by:
