[ Upstream commit 5ad992c71b6a8e8a547954addc7af9fbde6ca10a ]
clang-16 warns about casting functions to incompatible types, as is done here to call clk_disable_unprepare:
sound/soc/meson/t9015.c:274:4: error: cast from 'void (*)(struct clk *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict] 274 | (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.
