[PATCH 6.1 0378/1146] regulator: core: use kfree_const() to free space conditionally

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Wang ShaoBo <bobo.shaobowang@xxxxxxxxxx>

[ 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")
