This is a note to let you know that I've just added the patch titled
io: accel: kxcjk1013: restore the range after resume.
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.

On some laptops, kxcjk1013 is powered off when system enters S3. We need restore the range regiter during resume. Otherwise, the sensor doesn't work properly after S3.
