From d96a51f6b8040ef2b25b88032f23ffdb1ddba681 Mon Sep 17 00:00:00 2001 From: Dan Noe <dpn@isomerica.net> Date: Sat, 12 Apr 2008 22:34:38 -0400 Subject: [PATCH] cxgb3: Fix __must_check warning with dev_dbg. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fix the warning: drivers/net/cxgb3/cxgb3_main.c: In function ‘offload_open’: drivers/net/cxgb3/cxgb3_main.c:936: warning: ignoring return value of ‘sysfs_create_group’, declared with attribute warn_unused_result Now the return value is checked; if sysfs_create_group() returns failure, a warning is printed using dev_dbg, and the code continues as before. Use of dev_dbg ensures printk is not needlessly included unless desired for debugging.
