Subject: [PATCH] memory: ti-aemif: Handle return value of clk_prepare_enable
Date: Wed, 31 May 2017 15:55:54 +0530 [thread overview]
Message-ID: <0af185bb6358288552c16825e40c336542ced074.1496226063.git.arvind.yadav.cs@gmail.com> (raw)
clk_prepare_enable() can fail here and we must check its return value.
