From 74142ffc0b52cfe6f9d2f6f34a5f3eedbfe3ce51 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Fri, 20 Dec 2013 10:35:07 +0100 Subject: [PATCH] mfd: max77686: Fix regmap resource leak on driver remove The regmap used by max77686 MFD driver was not freed with regmap_exit() on driver exit. This lead to leak of resources. Replace regmap_init_i2c() call in driver probe with initialization of managed register map so the regmap will be properly freed by the device management code.
