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

iio: adis16400: Fix an error code in adis16400_initial_setup()

to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-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: Dan Carpenter dan.carpenter@oracle.com Date: Tue, 16 Feb 2021 22:42:13 +0300 Subject: iio: adis16400: Fix an error code in adis16400_initial_setup()

This is to silence a new Smatch warning:

drivers/iio/imu/adis16400.c:492 adis16400_initial_setup() warn: sscanf doesn't return error codes

If the condition "if (st->variant->flags & ADIS16400_HAS_SLOW_MODE) {" is false then we return 1 instead of returning 0 and probe will fail.
