clang-16 warns about casting functions to incompatible types, as is done here to call clk_disable_unprepare:

drivers/nvmem/meson-efuse.c:78:12: error: cast from 'void (*)(struct clk *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict] 78 | (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.
