In chasing down a previous issue with EDID probing from calling drm_helper_hpd_irq_event() from irq context, Laurent noticed that the DRM documentation suggests that drm_kms_helper_hotplug_event() should be used instead. Thus this patch replaces drm_helper_hpd_irq_event() with drm_kms_helper_hotplug_event(), which requires we update the connector.status entry and only call _hotplug_event() when the status changes.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
