[PATCH 6.3 043/246] watchdog: dw_wdt: Fix the error handling path of dw_wdt_drv_probe()

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

 



From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 7f5390750645756bd5da2b24fac285f2654dd922 ]

The commit in Fixes has only updated the remove function and missed the
error handling path of the probe.

Add the missing reset_control_assert() call.

Fixes: 65a3b6935d92 ("watchdog: dw_wdt: get reset lines from dt")
