[PATCH 2/4] media: i2c: ov2685: Add print for power on write failed

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

 



If the sensor doens't power up correctly, for example due to incorrect
devicetree description, the power up i2c writes will fail.

Add an error print for this situation.
