| Subject: i3c: master: svc: Fix missing STOP for master request |
| |
| From: Stanley Chu <yschu@nuvoton.com> |
| |
| [ Upstream commit 0430bf9bc1ac068c8b8c540eb93e5751872efc51 ] |
| |
| The controller driver nacked the master request but didn't emit a |
| STOP to end the transaction. The driver shall refuse the unsupported |
| requests and return the controller state to IDLE by emitting a STOP. |
