patch "iio: adc: ade9000: move mutex init before IRQ registration" 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: adc: ade9000: move mutex init before IRQ registration

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: adc: ade9000: move mutex init before IRQ registration

Move devm_mutex_init() before ade9000_request_irq() calls so that
st->lock is initialized before any handler that depends on it can run.
