From f84e27adfc4cb0c4aa97d830c43f8c82aca0547c Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Mon, 12 Oct 2015 17:21:26 +0100 Subject: [PATCH] staging: comedi: remove superfluous retval = 0 in comedi_read() `comedi_read()` initializes `retval` to 0. The other `retval = 0` assignments are superfluous, so remove them.
