Wentao Liang a51dedd586 PM: hibernate: Add error handling for syscore_suspend()
[ Upstream commit e20a70c572539a486dbd91b225fa6a194a5e2122 ]

In hibernation_platform_enter(), the code did not check the
return value of syscore_suspend(), potentially leading to a
situation where syscore_resume() would be called even if
syscore_suspend() failed. This could cause unpredictable
behavior or system instability.

Modify the code sequence in question to properly handle errors returned
by syscore_suspend(). If an error occurs in the suspend path, the code
now jumps to label 'Enable_irqs' skipping the syscore_resume() call and
only enabling interrupts after setting the system state to SYSTEM_RUNNING.

README

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.
