patch "iio: light: al3010: read both ALS ADC registers again" added to char-misc-testing

[<gregkh@linuxfoundation.org>]

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

    iio: light: al3010: read both ALS ADC registers again

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-testing 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 be merged to the char-misc-next branch sometime soon,
after it passes testing, and the merge window is open.

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

Subject: iio: light: al3010: read both ALS ADC registers again

al3010_read_raw() used to read two adjacent registers
until the driver was modernized using the regmap framework.
That cleanup accidentally replaced the 16-bit word read
with a single byte read. I'm reverting latter.
