Subject: [PATCH 0748/1085] drivers: media: cfe: Find the source pads on the
|
||
|
|
sensor entity
|
||
|
|
|
||
|
|
The driver was assuming that pad 0 on the sensor entity was the
|
||
|
|
appropriate source pad, but this isn't necessarily the case.
|
||
|
|
With video-mux, it has the sink pads first, and then the source
|
||
|
|
pad as the last one.
|
||
|
|
|
||
|
|
Iterate through the sensor pads to find the relevant source pads.
