The newly added exynos lpass driver produces a build warning when
CONFIG_PM is disabled since the only callers of exynos_lpass_disable
are under an #ifdef:drivers/mfd/exynos-lpass.c:93:13: error: 'exynos_lpass_disable' defined but not used [-Werror=unused-function]
static void exynos_lpass_disable(struct exynos_lpass *lpass)This removes the #ifdef and replaces it with __maybe_unused annotations
so the compiler can leave out the unused code silently with less
room for mistakes.Fixes: 36c26760bba8 ("mfd: Add Samsung Exynos Low Power Audio Subsystem driver")

This patch adds common driver for the Top block of the Samsung Exynos
SoC Low Power Audio Subsystem. This is a minimal driver which prepares
resources for IP blocks like I2S, audio DMA and UART and exposes
a regmap for the Top block registers. Also system power ops are added
to ensure the Audio Subsystem is operational after system suspend/resume
cycle.Signed-off-by: Inha Song
