| Subject: fsi/sbefifo: Clean up correct FIFO when receiving reset request from |
| SBE |
| |
| From: Joachim Fenkes <FENKES@de.ibm.com> |
| |
| [ Upstream commit 95152433e46fdb36652ebdbea442356a16ae1fa6 ] |
| |
| When the SBE requests a reset via the down FIFO, that is also the |
| FIFO we should go and reset ;) |
| |
| Fixes: 9f4a8a2d7f9d ("fsi/sbefifo: Add driver for the SBE FIFO") |
