From 3cf357dfb40b4a594a704f05b629cb5db97cc7fb Mon Sep 17 00:00:00 2001 From: Pramod Gurav Date: Wed, 6 Aug 2014 18:03:25 +0530 Subject: [PATCH] i2c: qup: disable clks and return instead of just returning error This fixes a error handling scenario where clocks were not being disabled when QUP_OUTPUT_BLOCK_SIZE returns a size greater than the size of blk_sizes array. So this patch adds a statement to jump to the fail lable to release the clocks. Signed-off-by: Pramod Gurav Acked-by: Ivan T.
