patch "uio/uio_pci_generic: fix return value changed in refactoring" added to char-misc-linus

[<gregkh@linuxfoundation.org>]

This is a note to let you know that I've just added the patch titled

    uio/uio_pci_generic: fix return value changed in refactoring

to my char-misc git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-linus branch.

The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.

If you have any questions about this process, please let me know.

Commit ef84928cff58 ("uio/uio_pci_generic: use device-managed function
equivalents") was able to simplify various error paths thanks to no
longer having to clean up on the way out. Some error paths were dropped,
others were simplified. In one of those simplifications, the return
value was accidentally changed from -ENODEV to -ENOMEM. Restore the old
return value.
