Subsystem:
libata pata arasan compact flash controller, libata subsystem (serial and parallel ata drivers), the rest · Maintainers:

From: Viresh Kumar <redacted>
clk_{un}prepare is mandatory for platforms using common clock framework. Since
this driver is used by SPEAr platform, which supports common clock framework,
add clk_{un}prepare() support for it.
