Subject: [PATCH] cxgb3: Fix __must_check warning with dev_dbg.
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
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.
