| Subject: ieee802154: cc2520: add rc code in cc2520_tx() |
| |
| From: Li Qiong <liqiong@nfschina.com> |
| |
| [ Upstream commit ffd7bdddaab193c38416fd5dd416d065517d266e ] |
| |
| 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. |
