patch "iio: pressure: ms5611: fixed value compensation bug" added to char-misc-linus

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

iio: pressure: ms5611: fixed value compensation bug

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: pressure: ms5611: fixed value compensation bug

When using multiple instances of this driver the compensation PROM was overwritten by the last initialized sensor. Now each sensor has own PROM storage.
