This is a note to let you know that I've just added the patch titled
iio:common:ssp_sensors: Fix an error handling path ssp_probe()
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.

If an error occurs after a successful mfd_add_devices() call, it should be undone by a corresponding mfd_remove_devices() call, as already done in the remove function.
