[PATCH 5.2 35/56] ocelot: Cancel delayed work before wq destruction

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

 



From: Claudiu Manoil <claudiu.manoil@xxxxxxx>

[ Upstream commit c5d139697d5d9ecf9c7cd92d7d7838a173508900 ]

Make sure the delayed work for stats update is not pending before
wq destruction.
This fixes the module unload path.
The issue is there since day 1.

Fixes: a556c76adc05 ("net: mscc: Add initial Ocelot switch support")
