patch "iio: gyro: mpu3050: Fix irq resource leak" added to char-misc-linus

[<gregkh@linuxfoundation.org>]

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

    iio: gyro: mpu3050: Fix irq resource leak

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.

Subject: iio: gyro: mpu3050: Fix irq resource leak

The interrupt handler is setup but only a few lines down if
iio_trigger_register() fails the function returns without properly
releasing the handler.

Add cleanup goto to resolve resource leak.

'irq' from request_threaded_irq() not released on lines: 1124.
