thermal: rcar_thermal: Prevent doing work after unbind
[ Upstream commit 697ee786f15d7b65c7f3045d45fe3a05d28e0911 ]
When testing bind/unbind on r8a7791/koelsch:
WARNING: CPU: 1 PID: 697 at lib/debugobjects.c:329 debug_print_object+0x8c/0xb4
ODEBUG: free active (active state 0) object type: timer_list hint: delayed_work_timer_fn+0x0/0x10
This happens if the workqueue runs after the device has been unbound.
Fix this by cancelling any queued work during remove.
Fixes: e0a5172e9eec7f0d ("thermal: rcar: add interrupt support")
