Subject: [PATCH] media: cx88: Fix some error handling path in 'cx8800_initdev()'
Git-commit: e1444e9b0424c70def6352580762d660af50e03f
Patch-mainline: v5.5-rc1
References: git-fixes

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)
