patch "iio: adc: ti-ads1119: Reinit completion before" added to char-misc-linus

[gregkh]

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

    iio: adc: ti-ads1119: Reinit completion before

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: ti-ads1119: Reinit completion before
 wait_for_completion_timeout()

The completion is not reinit before wait_for_completion_timeout(),
so wait_for_completion_timeout() will return immediately after
the first successful completion.
