From 75d63a40a5c01cf6ba9572cb124488a0e3baa6c1 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 10 Nov 2015 20:22:49 -0200 Subject: [PATCH] [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.
