Subject: media: i2c: ov5670: Fix PIXEL_RATE minimum value Author: Jacopo Mondi <[email protected]> Date: Mon Dec 21 18:52:20 2020 +0100 The driver currently reports a single supported value for V4L2_CID_PIXEL_RATE and initializes the control's minimum value to 0, which is very risky, as userspace might accidentally use it as divider when calculating the time duration of a line. Fix this by using as minimum the only supported value when registering the control.
