[ Upstream commit dc8d006d15b623c1d80b90b45d6dcb6e890dad09 ]
Use kfree_const() to free supply_name conditionally in create_regulator() as supply_name may be allocated from kmalloc() or directly from .rodata section.
Fixes: 87fe29b61f95 ("regulator: push allocations in create_regulator() outside of lock") Signed-off-by: Wang ShaoBo bobo.shaobowang@huawei.com Link: https://lore.kernel.org/r/20221123034616.3609537-1-bobo.shaobowang@huawei.co...
