[PATCH RESEND 01/13] power: reset: ltc2952: prefer devm_kzalloc over kzalloc

From: Frans Klaver <hidden>
Date: 2015-01-14 08:28:32
Also in: linux-pm, lkml
Subsystem: system reset/shutdown drivers, the rest · Maintainers: Sebastian Reichel, Linus Torvalds

Make use of the fact that the allocated resources can be automatically
deallocated. This reduces cleanup code and chance of leaks.
