This is a note to let you know that I've just added the patch titled
iio: gyro: fxas21002c: balance runtime power in error path
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.

If we fail to read temperature or axis we need to decrement the runtime pm reference count to trigger autosuspend.
Add the call to pm_put to do that in case of error.
