Subject: [PATCH] media: tw686x: Fix an error handling path in tw686x_probe()
The commit in Fixes: is incomplete. It has moved some code in the probe but
not all error handling paths have been updated.
Now, if request_irq() fails, we must release some resources.
Fixes: c8946454ed96 ("media: tw686x: Register the irq at the end of probe")
