5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jerome Brunet <jbrunet@xxxxxxxxxxxx>
[ Upstream commit cbd38332c140829ab752ba4e727f98be5c257f18 ]
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.
Fixes: 611fbca1c861 ("nvmem: meson-efuse: add peripheral clock")
