[PATCH] regulator: core: use kfree_const() to free space conditionally

From: Wang ShaoBo
Date: Tue Nov 22 2022 - 22:50:57 EST


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")
