commit 19df76662a33d2f2fc41a66607cb8285fc02d6ec upstream. This reverts commit35781d8356. Hibernation is not supported on Qualcomm platforms with mainline kernels yet a broken vendor implementation for the GENI serial driver made it upstream. This is effectively dead code that cannot be tested and should just be removed, but if these paths were ever hit for an open non-console port they would crash the machine as the driver would fail to enable clocks during restore() (i.e. all ports would have to be closed by drivers and user space before hibernating the system to avoid this as a comment in the code hinted at). The broken implementation also added a random call to enable the receiver in the port setup code where it does not belong and which enables the receiver prematurely for console ports.

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.
