This is a note to let you know that I've just added the patch titled
iio: gyro: mpu3050: Fix the error handling in mpu3050_power_up()
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.

The driver should disable regulators when fails at regmap_update_bits().
