Pull media updates from Mauro Carvalho Chehab:

 - the old V4L2 core videobuf kAPI was finally removed. All media
   drivers should now be using VB2 kAPI

 - new automotive driver: mgb4

 - new platform video driver: npcm-video

 - new sensor driver: mt9m114

 - new TI driver used in conjunction with Cadence CSI2RX IP to bridge
   TI-specific parts

 - ir-rx51 was removed and the N900 DT binding was moved to the
   pwm-ir-tx generic driver

 - drop atomisp-specific ov5693, using the upstream driver instead

 - the camss driver has gained RDI3 support for VFE 17x

 - the atomisp driver now detects ISP2400 or ISP2401 at run time. No
   need to set it up at build time anymore

 - lots of driver fixes, cleanups and improvements

Need to use encoder device to allocate/free encoder memory when calling
mtk_vcodec_mem_alloc/mtk_vcodec_mem_free, or leading to below crash log
when test encoder with decoder device.

Remove PM functions at start/stop streaming, add PM helper functions
to get PM before encoding frame start and put PM after encoding frame
done. Meanwhile, remove unnecessary clock operations.

Pull media updates from Mauro Carvalho Chehab:

 - new i2c drivers: ds90ub913, ds90ub953, ds90ub960, dw9719, ds90ub913

 - new Intel IVSC MEI drivers

 - some Mediatek platform drivers were moved to a common location

 - Intel atomisp2 driver is now working with the main ov2680 driver. Due
   to that, the atomisp2 ov2680 staging one was removed

 - the bttv driver was finally converted to videobuf2 framework. This
   was the last one upstream using videobuf version 1 core. We'll likely
   remove the old videobuf framework on 6.7

 - lots of improvements at atomisp driver: it now works with normal I2C
   sensors. Several compile-mode dependecies to select between ISP2400
   and ISP2401 are now solved in runtime

 - a new ipu-bridge logic was added to work with IVSC MEI drivers

 - venus driver gained better support for new VPU versions

 - the v4l core async framework has gained lots of improvements and
   cleanups

 - lots of other cleanups, improvements and driver fixes

Pull media updates from Mauro Carvalho Chehab:

 - new i2c drivers: ds90ub913, ds90ub953, ds90ub960, dw9719, ds90ub913

 - new Intel IVSC MEI drivers

 - some Mediatek platform drivers were moved to a common location

 - Intel atomisp2 driver is now working with the main ov2680 driver. Due
   to that, the atomisp2 ov2680 staging one was removed

 - the bttv driver was finally converted to videobuf2 framework. This
   was the last one upstream using videobuf version 1 core. We'll likely
   remove the old videobuf framework on 6.7

 - lots of improvements at atomisp driver: it now works with normal I2C
   sensors. Several compile-mode dependecies to select between ISP2400
   and ISP2401 are now solved in runtime

 - a new ipu-bridge logic was added to work with IVSC MEI drivers

 - venus driver gained better support for new VPU versions

 - the v4l core async framework has gained lots of improvements and
   cleanups

 - lots of other cleanups, improvements and driver fixes

variable *nplanes is provided by user via system call argument. The
possible value of q_data-&gt;fmt-&gt;num_planes is 1-3, while the value
of *nplanes can be 1-8. The array access by index i can cause array
out-of-bounds.

Fix this bug by checking *nplanes against the array size.

The vpu maybe null pointer or unreasonable value when scp crash, need to
validate that the vpu pointer and the vpu instance within this context is
valid in case of leading to kernel reboot.
