Subject: [PATCH net-next 0/2] Fixes to allow mv88e6xxx module to be reloaded
Date: Mon, 19 Mar 2018 22:16:19 +0100 [thread overview]
Message-ID: <1521494181-4653-1-git-send-email-andrew@lunn.ch> (raw)
As reported by Uwe Kleine-K�nig, the interrupt trigger is first
configured by DT and then reconfigured to edge. This results in a
failure on EPROBE_DEFER, or if the module is unloaded and reloaded.
A second crash happens on module reload due to a missing call to the
common IRQ free code when using polled interrupts.
With these fixes in place, it becomes possible to load and unload the
kernel modules a few times without it crashing.
