Gustavo A. R. Silva c2e1ce4fa4 ARM: OMAP2+: Fix -Warray-bounds warning in _pwrdm_state_switch() 
commit 847fb80cc01a54bc827b02547bb8743bdb59ddab upstream.

If function pwrdm_read_prev_pwrst() returns -EINVAL, we will end
up accessing array pwrdm->state_counter through negative index
-22. This is wrong and the compiler is legitimately warning us
about this potential problem.

Fix this by sanity checking the value stored in variable _prev_
before accessing array pwrdm->state_counter.

Address the following -Warray-bounds warning:
arch/arm/mach-omap2/powerdomain.c:178:45: warning: array subscript -22 is below array bounds of 'unsigned int[4]' [-Warray-bounds]

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.
