Merge tag 'media/v5.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab: - a new sensor driver for ov5675 - a new platform driver for Allwinner A10 sensor interface - some new remote controller keymaps - some cosmetic changes at V4L2 core in order to avoid #ifdefs and to merge two core modules into one - removal of bcm2048 radio driver from staging - removal of davinci_vpfe video driver from staging - regression fix since Kernel 5.1 at the legacy VideoBuffer version 1 core - added some documentation for remote controller protocols - pixel format documentation was split on two files - lots of other driver improvements and cleanups * tag 'media/v5.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (321 commits) media: videobuf-core.c: poll_wait needs a non-NULL buf pointer media: sun4i: Make sun4i_csi_formats static media: imx: remove unused including <linux/version.h> media: stm32-dcmi: Delete an unnecessary of_node_put() call in dcmi_probe() media: pvrusb2: qctrl.flag will be uninitlaized if cx2341x_ctrl_query() returns error code media: em28xx: Fix exception handling in em28xx_alloc_urbs() media: don't do a 31 bit shift on a signed int media: use the BIT() macro media: ov9650: add a sanity check media: aspeed-video: address a protential usage of an unitialized var media: vicodec: make life easier for static analyzers media: remove include stdarg.h from some drivers v4l2-core: fix coding style for the two new c files media: v4l2-core: Remove BUG() from i2c and spi helpers media: v4l2-core: introduce a helper to unregister a i2c subdev media: v4l2-core: introduce a helper to unregister a spi subdev media: v4l2-core: move i2c helpers out of v4l2-common.c media: v4l2-core: move spi helpers out of v4l2-common.c media: v4l2-core: Module re-organization media: usbvision: Remove dead code ...
