Date: Fri, 4 Apr 2008 09:21:53 -0400 From: Dan Noe <dpn@...merica.net> To: linux-kernel@...r.kernel.org Cc: kernel-janitors@...r.kernel.org, Dan Noe <dpn@...merica.net> Subject: [PATCH] cxgb3: Fix __must_check warning from call to sysfs_create_group. 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. The original driver code chose to ignore failure of sysfs_create_group, and this has not been changed beyond a warning when DEBUG is enabled.
