[PATCH 3.14 024/130] iw_cxgb3: Fix incorrectly returning error on success

From: Greg Kroah-Hartman
Date: Tue Mar 01 2016 - 21:09:45 EST


3.14-stable review patch. If anyone has any objections, please let me know.

------------------

From: Hariprasad S <hariprasad@xxxxxxxxxxx>

commit 67f1aee6f45059fd6b0f5b0ecb2c97ad0451f6b3 upstream.

The cxgb3_*_send() functions return NET_XMIT_ values, which are
positive integers values. So don't treat positive return values
as an error.
