[PATCH 0/2] media: synopsys: csi2rx: various fixes

[Michael Riesch via B4 Relay]

Habidere,

This series contains two fixes that address two issues raised by
CI bots.

1) A stupid off-by-one mistake in the check that protects the formats
   array. Thanks to Dan and his smatch bot.

2) A missing Kconfig dependency discovered by the lkp bot.

At this point, thanks to all the people that maintain those bots/the
CI infrastructure!

Best regards,
Michael

[Michael Riesch via B4 Relay]

From: Michael Riesch <michael.riesch@collabora.com>

The out-of-bounds check for the format array is off by one. Fix the
check.
