cxgb3: Fix __must_check warning with dev_dbg.
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. Signed-off-by: Dan Noe <dpn@isomerica.net> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
