From 51d0420b0ad9f0a9972165fef551628bcc95ee87 Mon Sep 17 00:00:00 2001 From: Emil Tantilov Date: Fri, 18 Jan 2013 02:17:11 +0000 Subject: [PATCH] ixgbe: cleanup error checking in ixgbe_identify_sfp_module_generic() This patch replaces instances where a return code from i2c operations were checked against a list of error codes with a much simpler if ( status != 0 ) check. Some whitespace cleanups included.
