From 7c4c25e4bc37672e68d1c480a81fcb0efe6d2006 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Fri, 6 Aug 2010 13:33:15 +0800 Subject: regulator: max1586 - fix a memory leak in max1586_pmic_remove() In max1586_pmic_probe(), we allocate memory for max1586. In max1586_pmic_remove(), current implementation only free rdev which is a member of struct max1586_data. Thus, there is a small memory leak when we unload the module. This patch fixes the memory leak by passing max1586 to i2c clientdata, and properly kfree(max1586) in max1586_pmic_remove().
