Osama Abdelkader b28cf21422 drm/bridge: megachips: remove bridge when irq request fails 
commit d45d5c819f upstream.

If devm_request_threaded_irq() fails after drm_bridge_add(), remove the
bridge before returning.

Keep drm_bridge_add() rather than devm_drm_bridge_add(): registration is
tied to the STDP4028 device while ge_b850v3_register() may complete from
either I2C probe; devm would not unwind the bridge if the other client's
probe fails.

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.
