Subject: [media] s5h1420: Unused variable clock_setting
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3f7c0a69ab1181a0f5e4ead5d4b270d404c6465c;p=linux-beck.git

[media] s5h1420: Unused variable clock_setting

The switch/case was setting clock_setting that is not being used. Both switch/case and the variable definition were removed.

Currently clock is being calculated by the formula:
(state->fclk/1000000 - 8)

Tested by compilation only.
