[PATCH 12/20] media: atomisp: get rid of a warning message

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

 



There's a warning message about an unused code. The code that
were using it were commented out, due to a problem causing the
firmware load to fail on the machines we're using for testing.

Change the place where we're commenting the code out, in order
to avoid the warning.

Fixes: 95d1f398c4dc ("media: atomisp: keep the ISP powered on when setting it")
