5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold johan+linaro@kernel.org
commit e3d86847fba58cf71f66e81b6a2515e07039ae17 upstream.
Probe deferral should not be logged as an error:
ov8856 24-0010: failed to get HW configuration: -517
Use dev_err_probe() for the clock lookup and drop the (mostly) redundant dev_err() from sensor probe() to suppress it.
Note that errors during regulator lookup is already correctly logged using dev_err_probe().
