patch "iio: adc: rohm-bd79124: Fix channel initialization" added to char-misc-linus

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

iio: adc: rohm-bd79124: Fix channel initialization

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: rohm-bd79124: Fix channel initialization

The alarm limit register on BD79124 span to two consecutive registers. The first register for high-limit containing also hysteresis configuration. The initialization in driver writes only one 8-bit register, overwriting the hysteresis and leaving the other limit register uninitialized.

Fix the limit initialization by using the bd79124_write_int_to_reg(), which correctly initializes the limit on both of the registers.
