[PATCH 6.9 039/157] media: ov2740: Fix LINK_FREQ and PIXEL_RATE control value reporting

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sakari Ailus <sakari.ailus@xxxxxxxxxxxxxxx>

commit f7aa5995910cb5e7a5419c6705f465c55973b714 upstream.

The driver dug the supported link frequency up from the V4L2 fwnode
endpoint and used it internally, but failed to report this in the
LINK_FREQ and PIXEL_RATE controls. Fix this.

Fixes: 0677a2d9b735 ("media: ov2740: Add support for 180 MHz link frequency")
Cc: stable@xxxxxxxxxxxxxxx # for v6.8 and later
