media: platform: imx-mipi-csis: Add dependency on VIDEO_DEV

2022-04-05T23:57:35+00:00

The imx-mipi-csis driver (VIDEO_IMX_MIPI_CSIS) lost its dependency on
VIDEO_DEV in commit 63fe3d27b226 ("media: platform/*/Kconfig: make
manufacturer menus more uniform"). This causes build failures with
configurations that don't have VIDEO_DEV set. Fix it by restoring the
dependency.

The imx-mipi-csis driver is specific to NXP platforms. Restrict it to
those by default, and enable compilation with COMPILE_TEST to keep a
wide test coverage.

media: platform: Remove unnecessary print function dev_err()

2022-03-18T05:05:43+00:00

The print function dev_err() is redundant because platform_get_irq()
already prints an error.

Eliminate the follow coccicheck warnings:
./drivers/media/platform/mediatek/vcodec/mtk_vcodec_dec_drv.c:119:2-9:
line 119 is redundant because platform_get_irq() already prints an error

line 103 is redundant because platform_get_irq() already prints an error
