From 7764d0cdc3dbf15010f66e0e2e5786f0f03d402a Mon Sep 17 00:00:00 2001 From: Vaibhav Hiremath Date: Wed, 22 Jul 2015 15:04:53 +0530 Subject: [PATCH] clk: s2mps11: Use kcalloc instead of kzalloc for array allocation This patch cleans up the driver for, - Use devm_kcalloc() variant instead of devm_kzalloc() for array allocation. - clk_prepare()/unprepare(), remove "ret" variable as it is not required - use __exit for cleanup function As I am referring this driver as a reference for my 88pm800 clk driver, applying same changes here as well.
