[Why] Similar to SST branch, gpio conflict also needs to be avoided on MST. Without doing so, there is a chance that gpio conflict will occur if multiple gpio interrupts arrive simultaneously. [How] By mutex locking/unlocking &aconnector->hpd_lock, we won't get gpio conflict when handling hpd.

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.
