Thanks. I'll send a v2 with changes and your review. Best regards, Krzysztof

COMMON_CLK is a user-selectable option with its own dependencies. The most important dependency is !HAVE_LEGACY_CLK. User-selectable drivers should not select COMMON_CLK because they will create a dependency cycle and build failures. For example on MIPS a configuration with COMMON_CLK (selected by SND_SUN8I_CODEC) and HAVE_LEGACY_CLK (selected by SOC_RT305X) is possible: WARNING: unmet direct dependencies detected for COMMON_CLK Depends on [n]: !HAVE_LEGACY_CLK [=y] Selected by [y]: - SND_SUN8I_CODEC [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && (ARCH_SUNXI || COMPILE_TEST [=y]) && OF [=y] && (MACH_SUN8I || ARM64 && ARCH_SUNXI || COMPILE_TEST [=y]) /usr/bin/mips-linux-gnu-ld: drivers/clk/clk.o: in function `clk_set_rate': (.text+0xaeb4): multiple definition of `clk_set_rate'; arch/mips/ralink/clk.o:(.text+0x88): first defined here Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> --- arch/arm/mach-sunxi/Kconfig | 1 + sound/soc/sunxi/Kconfig | 2 +- 2 files changed, 2 insertions(+), 1 deletion(-)
