Subsystems (2)
This is a note to let you know that I've just added the patch titled
iio: imu: fxos8700: fix incomplete ACCEL and MAGN channels readback
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.)

Subject: iio: imu: fxos8700: fix incomplete ACCEL and MAGN channels readback
The length of ACCEL and MAGN 3-axis channels output data is 6 byte individually. However block only read 3 bytes data into buffer from ACCEL or MAGN output data registers every time. It causes an incomplete ACCEL and MAGN channels readback.
Set correct value count for regmap_bulk_read to get 6 bytes ACCEL and MAGN channels readback.
