Subject[PATCH AUTOSEL 4.9 2/8] net: microchip: encx24j600: add missed kthread_stop
Date
From: Chuhong Yuan <hslester96@gmail.com>

[ Upstream commit ff8ce319e9c25e920d994cc35236f0bb32dfc8f3 ]

This driver calls kthread_run() in probe, but forgets to call
kthread_stop() in probe failure and remove.
Add the missed kthread_stop() to fix it.
