X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8974b76ddc933151395db6085bf49fad8cd0346b;p=linux.git

video: fbdev: tridentfb: remove deadcode on unreachable case statement

The value of tmp being used in the switch statement has the range of
just 0..3 hence the case 4 statement can never be reached and is
deadcode and can be removed.

Detected by CoverityScan, CID#744384 ("Logically dead code")
