[ Upstream commit 98ac85a00f31d2e9d5452b825a9ed0153d934043 ]
clang-16 warns about casting functions to incompatible types, as is done here to call clk_disable_unprepare:
sound/soc/meson/aiu.c:243:12: error: cast from 'void (*)(struct clk *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict] 243 | (void(*)(void *))clk_disable_unprepare,
The pattern of getting, enabling and setting a disable callback for a clock can be replaced with devm_clk_get_enabled(), which also fixes this warning.
