Subject: [media] rtl2832: fix compiler warning
X-Git-Tag: v4.1-rc1~59^2~1^2~205
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f2e37b9b733c720de917aa7616cce3a1c52225eb;p=karo-tx-linux.git

[media] rtl2832: fix compiler warning

>From the daily build:

rtl2832.c: In function 'rtl2832_read_status':
rtl2832.c:703:12: warning: 'tmp' may be used uninitialized in this function [-Wmaybe-uninitialized]
  } else if (tmp == 10) {
            ^

The code is OK, it's just the compiler that cannot figure out what's
going on. So just init 'tmp' to 0.
