[PATCH v1 3/3] i3c: master: svc: Fix missing STOP for master request

From: Stanley Chu
Date: Mon Mar 17 2025 - 01:20:38 EST


From: Stanley Chu <yschu@xxxxxxxxxxx>

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.

Fixes: dd3c52846d59 ("i3c: master: svc: Add Silvaco I3C master driver")
