Subject: [PATCH 5/8] media: imx: imx7_mipi_csis: store colorspace in set_fmt as well

Without this the default (SMPTE 170M) from init_cfg stays unchanged.
Even after configuring 'srgb' colorspace (or 'raw')
$ media-ctl -V "'csis-32e30000.mipi-csi':0 [colorspace:srgb]"
the colorspace does not change at all:
$ media-ctl --get-v4l2 "'csis-32e30000.mipi-csi':0"
[fmt:SRGGB10_1X10/1920x1080 field:none colorspace:smpte170m xfer:709
ycbcr:601 quantization:lim-range]

Looks good, but shouldn't you also store the other colorspace-related
fields (ycbcr_enc, quantization and xfer_func) ?

Thanks for that feedback. Sounds reasonable, will do that.
