This is a note to let you know that I've just added the patch titled
Revert "tty: serial: bcm63xx: fix missing clk_put() in bcm63xx_uart"
to my tty git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git
in the tty-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.

Subject: Revert "tty: serial: bcm63xx: fix missing clk_put() in bcm63xx_uart"
This reverts commit 580d952e44de5509c69c8f9346180ecaa78ebeec ("tty:
serial: bcm63xx: fix missing clk_put() in bcm63xx_uart") because we
should not be doing a clk_put() if we were not successful in getting a
valid clock reference via clk_get() in the first place.
