[PATCH] media: i2c: ov5670: Fix PIXEL_RATE minimum value

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

 



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.

Take #2. I sent it out yesterday but apparantly it didn't hit the list.
Some of you will receive it multiple times, sorry about this.
