From 55e44791a547830b2906dd364afae2a1ec49a401 Mon Sep 17 00:00:00 2001 From: Wang ShaoBo Date: Wed, 23 Nov 2022 11:46:16 +0800 Subject: [PATCH] regulator: core: use kfree_const() to free space conditionally [ 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.
