Use the correct function name and modify the function short description. This prevents a kernel-doc warning: drivers/regulator/fixed-helper.c:32: warning: expecting prototype for regulator_register_fixed_name(). Prototype was for regulator_register_always_on() instead Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Liam Girdwood <lgirdwood@gmail.com> Cc: Mark Brown <broonie@kernel.org> Link: https://lore.kernel.org/r/20230113064421.11986-1-rdunlap@infradead.org Signed-off-by: Mark Brown <broonie@kernel.org>
