Subject: gpio-rcar: Remove #ifdef CONFIG_OF around OF-specific sections
X-Git-Tag: next-20130628~12^2~1^9
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e305062e94719ef543ae936dd56501b5a36406c6;p=karo-tx-linux.git

gpio-rcar: Remove #ifdef CONFIG_OF around OF-specific sections

All functions and data types used by OF-specific code paths are declared
in <linux/of.h> regardless of CONFIG_OF. Replace the #ifdef CONFIG_OF
guard with a if(IS_ENABLED(CONFIG_OF)) and let the compiler optimize
the unused code away.
