This patch fixes the BT power reported the failure message.
As following:
root@linaro-alip:~# echo 1 > /sys/class/rfkill/rfkill0/state
[ 892.558269] rockchip-pinctrl pinctrl: pin gpio0-19 already requested
by 20060000.serial; cannot claim for wireless-bluetooth
[ 892.571052] rockchip-pinctrl pinctrl: pin-19 (wireless-bluetooth) status -22
...
And for now, the BT can work with this patch.
root@linaro-alip:~# echo 1 > /sys/class/rfkill/rfkill0/state

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
