Subject: [PATCH] [media] cx88: Fix some error handling path in 'cx8800_initdev()'
Date: Sun, 22 Sep 2019 09:41:23 +0200 [thread overview]
Message-ID: <20190922074123.29124-1-christophe.jaillet@wanadoo.fr> (raw)
A call to 'pci_disable_device()' is missing in the error handling path.
In some cases, a call to 'free_irq()' may also be missing.
Reorder the error handling path, add some new labels and fix the 2 issues
mentionned above.
This way, the error handling path in more in line with 'cx8800_finidev()'
(i.e. the remove function)

It is likely that this is still incomplete, but at least it should be
better :)
