Subject: ieee802154: cc2520: add rc code in cc2520_tx()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ffd7bdddaab193c38416fd5dd416d065517d266e;p=linux.git

ieee802154: cc2520: add rc code in cc2520_tx()

The rc code is 0 at the error path "status & CC2520_STATUS_TX_UNDERFLOW".
Assign rc code with '-EINVAL' at this error path to fix it.
