7cd7120296If set active without increase the usage count of pm, the dont use
autosuspend function will call the suspend callback to close the two
clocks of spi because the usage count is reduced to -1.
This will cause the warning dump below when the defer-probe occurs.

[ 129.384005] WARNING: CPU: 1 PID: 33 at drivers/clk/clk.c:952 clk_core_disable+0xa4/0xb0

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.
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.
