[PATCH] [media] cx88: Fix some error handling path in 'cx8800_initdev()'

From: Christophe JAILLET
Date: Sun Sep 22 2019 - 03:41:49 EST


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 :)
