The MCA driver selects COMMON_CLK, which leads to misconfiguration
on platforms with HAVE_LEGACY_CLK (under compile test). Kconfig catches
the conflict with the following warning:
WARNING: unmet direct dependencies detected for COMMON_CLK
Depends on [n]: !HAVE_LEGACY_CLK [=y]
Selected by [m]:
- SND_SOC_APPLE_MCA [=m] && SOUND [=m] && !UML && SND [=m] &&
SND_SOC [=m] && (ARCH_APPLE || COMPILE_TEST [=y])
Eventually the build fails with errors like:
>> drivers/clk/clk.c:867:6: error: redefinition of 'clk_unprepare'
867 | void clk_unprepare(struct clk *clk)
| ^~~~~~~~~~~~~
In file included from drivers/clk/clk.c:9:
include/linux/clk.h:303:20: note: previous definition of 'clk_unprepare' with type 'void(struct clk *)'
303 | static inline void clk_unprepare(struct clk *clk)
| ^~~~~~~~~~~~~
which appears to be because COMMON_CLK is selected but HAVE_CLK_PREPARE
is not. In the end it seems we had no business selecting COMMON_CLK from
an unrelated driver like that, so remove the selection. The linux/clk.h
API is there anyway.
