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.)
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.
From 37a94d86d7050665d6d01378b2c916c28e454f10 Mon Sep 17 00:00:00 2001 From: Carlos Song carlos.song@nxp.com Date: Thu, 8 Dec 2022 15:19:07 +0800 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.
