From dfa30ac13952ee0c2918090815688a909ad074f0 Mon Sep 17 00:00:00 2001 From: Daeseok Youn Date: Tue, 15 Jul 2014 18:47:11 +0900 Subject: staging: dgap: remove redundant error value check The retval in dgap_block_til_ready() is initialized to zero, and if no error has occurred in this function, the retval has a zero. So it doesn't need to check "retval" itself.
