[PATCH 5.15 180/203] can: kvaser_pciefd: Clear listen-only bit if not explicitly requested

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jimmy Assarsson <extja@xxxxxxxxxx>

commit bf7ac55e991ca177f1ac16be51152f1ef291a4df upstream.

The listen-only bit was never cleared, causing the controller to
always use listen-only mode, if previously set.

Fixes: 26ad340e582d ("can: kvaser_pciefd: Add driver for Kvaser PCIEcan devices")
