media: i2c: ov01a10: Fix digital gain range

[ Upstream commit 91848c99ed6a98daf77f4cb7d44cf3f13bc6998f ] Digital gain wraps-around at the maximum of 16838 / 0x3fff. Fix the maximum digital gain by setting it to 0x3fff.

media: i2c: ov5647: use our own mutex for the ctrl lock

2026-03-04T12:21:03+00:00

[ Upstream commit 973e42fd5d2b397bff34f0c249014902dbf65912 ] __v4l2_ctrl_handler_setup() and __v4l2_ctrl_modify_range() contains an assertion to verify that the v4l2_ctrl_handler::lock is held, as it should only be called when the lock has already been acquired. Therefore use our own mutex for the ctrl lock, otherwise a warning will be reported.
