[PATCH V3 07/12] ata/sata_mv: Remove conditional compilation of clk code

Viresh Kumar viresh.kumar at st.com
Tue Apr 24 07:21:29 EDT 2012


With addition of dummy clk_*() calls for non CONFIG_HAVE_CLK cases in clk.h,
there is no need to have clk code enclosed in #ifdef CONFIG_HAVE_CLK, #endif
macros.
