Subject: iwlegacy: propagate error return value
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=5c30c76ee616fffb47cbd9810bfd0a99ce4ddb38;p=openwrt%2Fstaging%2Fblogic.git

iwlegacy: propagate error return value

propogate the return value from iwl4965_get_tx_atten_grp instead
of implicitly returning -EINVAL in the error case.
