This is a note to let you know that I've just added the patch titled
iio: imu: fxos8700: fix failed initialization ODR mode assignment
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 eb6d8f8705bc19141bac81d8161461f9e256948a Mon Sep 17 00:00:00 2001 From: Carlos Song carlos.song@nxp.com Date: Wed, 18 Jan 2023 15:42:25 +0800 Subject: iio: imu: fxos8700: fix failed initialization ODR mode assignment
The absence of correct offset leads a failed initialization ODR mode assignment.
Select MAX ODR mode as the initialization ODR mode by field mask and FIELD_PREP.
