2019-07-25media: sh_veu: convert to struct v4l2_fhHans Verkuil1-0/+5
This driver didn't use struct v4l2_fh, so add it. This is a very basic conversion. I can't test this on real hardware, so I didn't dare to also convert the driver to start using the v4l2-mem2mem ioctl/fop helpers.

2019-07-23media: vivid: work around high stack usage with clangArnd Bergmann1-3/+4
Building a KASAN-enabled kernel with clang ends up in a case where too much is inlined into vivid_thread_vid_cap() and the stack usage grows a lot, possibly when the register allocation fails to produce efficient code and spills a lot of temporaries to the stack. This uses more than twice the amount of stack than the sum of the individual functions when they are not inlined: drivers/media/platform/vivid/vivid-kthread-cap.c:766:12: error: stack frame size of 2208 bytes in function 'vivid_thread_vid_cap' [-Werror,-Wframe-larger-than=] Marking two of the key functions in here as 'noinline_for_stack' avoids the pathological case in clang without any apparent downside for gcc.

The V4L2 core sets the format description and flags for the driver in order to ensure consistent naming. So drop the strscpy of the description in drivers. Also remove any description strings in driver-internal structures since those are no longer needed. And in am437x-vpfe.c drop an unnecessary f->type assignment in vpfe_enum_fmt().

2019-06-27media: cec: add struct cec_connector_info supportDariusz Marcinkiewicz1-1/+1
Define struct cec_connector_info in media/cec.h and define CEC_CAP_CONNECTOR_INFO. In a later patch this will be moved to uapi/linux/cec.h. The CEC_CAP_CONNECTOR_INFO capability can be set by drivers, but cec_allocate_adapter() will remove it again until the public API for this can be enabled once all drm drivers wire this up correctly. Also add the cec_fill_conn_info_from_drm and cec_s_conn_info functions, which are needed by drm drivers to fill in the cec_connector info based on a drm_connector. The cec_notifier_(un)register and cec_register_cec_notifier prototypes were moved from cec-notifier.h to cec.h since cec.h no longer includes cec-notifier.h. These headers included each other before, which caused various problems. Due to these changes the seco-cec driver was changed as well: it should include cec-notifier.h, not cec.h.

2019-06-24media: vimc: cap: check v4l2_fill_pixfmt return valueAndré Almeida1-1/+4
v4l2_fill_pixfmt() returns -EINVAL if the pixelformat used as parameter is invalid or if the user is trying to use a multiplanar format with the singleplanar API. Currently, the vimc_cap_try_fmt_vid_cap() returns such value, but vimc_cap_s_fmt_vid_cap() is ignoring it. Fix that and returns an error value if vimc_cap_try_fmt_vid_cap() has failed.
