From ff2b7ac6f6c58b0011d9d73004fb6e396f514018 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Fri, 8 Jun 2012 08:35:37 +0800 Subject: [PATCH] mfd: Fix max77693 irq leak and wrong kfree call We need to call max77693_irq_exit() in max77693_i2c_probe error patch and max77693_i2c_remove. Current code already uses devm_kzalloc() to allocate memory for max77693. Thus we should not call kfree(max77693), otherwise we got double free.
