Benjamin Tissoires 5dc297652d HID: mcp-2221: prevent UAF in delayed work 
commit 47e91fdfa5 upstream.

If the device is plugged/unplugged without giving time for mcp_init_work()
to complete, we might kick in the devm free code path and thus have
unavailable struct mcp_2221 while in delayed work.

Canceling the delayed_work item is enough to solve the issue, because
cancel_delayed_work_sync will prevent the work item to requeue itself.

Fixes: 960f9df7c6 ("HID: mcp2221: add ADC/DAC support via iio subsystem")
