Subject: ARM: OMAP2+: powerdomain.c: Remove some unused functions
X-Git-Tag: v4.0-rc1~71^2~9^2~9
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=10637afb9157c5da28aef0465cd9e6135af5148b;p=karo-tx-linux.git

ARM: OMAP2+: powerdomain.c: Remove some unused functions

Removes some functions that are not used anywhere:
pwrdm_get_voltdm() pwrdm_for_each_clkdm() pwrdm_del_clkdm()

This was partially found by using a static code analysis program called cppcheck.
