Into alvium cameras REG_BCRM_GAIN_RW control the analog gain.
Let's use the right V4L2_CID_ANALOGUE_GAIN ctrl.

This looks like a bugfix. Shouldn't it be cc'd to stable as well? A Fixes:
tag would be nice, too.

Fully agree.
Plan is to add in v2 Fixes: 0a7af872915e ("media: i2c: Add support for alvium camera")
like you suggest and stable@vger.kernel.org in CC.

Just make sure git send-email won't actually cc the patch to the stable
e-mail address. Cc: tag is enough. The git config option is
sendemail.suppresscc.

Sorry, just to clarify.
You are suggesting just to add sendemail.suppresscc. option right?
No cc stable@vger.kernel.org
