patch "iio: pressure: ms5611: changed hardcoded SPI speed to value limited" added to char-misc-linus

[gregkh]

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

    iio: pressure: ms5611: changed hardcoded SPI speed to value limited

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: changed hardcoded SPI speed to value limited

Don't hardcode the ms5611 SPI speed, limit it instead.
