patch "iio: ssp_sensors: fix error code in ssp_print_mcu_debug()" added to staging-linus

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

iio: ssp_sensors: fix error code in ssp_print_mcu_debug()

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.

Subject: iio: ssp_sensors: fix error code in ssp_print_mcu_debug()

The ssp_print_mcu_debug() function should return negative error codes on error. Returning "length" is meaningless. This change does not affect runtime because the callers only care about zero/non-zero.
