COMMON_CLK should not be used when legacy clocks are provided by architecture, so it correctly depends on !HAVE_LEGACY_CLK. However it is possible to create a config which selects both COMMON_CLK (by SND_SUN8I_CODEC) and HAVE_LEGACY_CLK (by SOC_RT305X) which leads to compile errors (MIPS architecture): drivers/clk/clk.c:855:6: error: redefinition of ‘clk_unprepare’ In file included from drivers/clk/clk.c:9: include/linux/clk.h:263:20: note: previous definition of ‘clk_unprepare’ was here The definitions clk_bulk_prepare() (and unprepare) already have proper surrounding #ifdef so add them also for clk_prepare()/clk_unprepare().
