Subject: media: tw5864: Simplify 'tw5864_finidev()'
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=901181b7ff1659893f8714a7752465a9b719f19f;p=linux.git

media: tw5864: Simplify 'tw5864_finidev()'

Some resources are allocated with 'pci_request_regions()', so use
'pci_release_regions()' to free them, instead of a verbose
'release_mem_region()'.

There is no point in calling 'devm_kfree()'. The corresponding resource is
managed, so it will be fried automatically.
