patch "iio: adis16475: fix deadlock on frequency set" added to staging-linus

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

iio: adis16475: fix deadlock on frequency set

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.

With commit 39c024b51b560
("iio: adis16475: improve sync scale mode handling"), two deadlocks were introduced:
1) The call to 'adis_write_reg_16()' was not changed to it's unlocked version.
2) The lock was not being released on the success path of the function.

This change fixes both these issues.
