Subject: [PATCH 8/8] s5h1420: Unused variable clock_setting
Newsgroups: gmane.linux.drivers.video-input-infrastructure
Date: Thursday 14th June 2012 17:58:16 UTC (over 5 years ago)
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.
