Subject[patch 1/2] [media] av7110: don't allow negative volumes
The issue here is that we there is a static checker warning because we
have a user controlled volume setting and we cap the upper bound but we
allow negative numbers. Negative volumes don't make sense, so let's
make these variables unsigned.
