drm/i915: Disable HPD interrupt on pin when irq storm is detected (v3)
This patch disables hotplug interrupts if an 'interrupt storm'
has been detected.
Noise on the interrupt line renders the hotplug interrupt useless:
each hotplug event causes the devices to be rescanned which will
will only increase the system load.
Thus disable the hotplug interrupts and fall back to periodic
device polling.
v2: Fixed cleanup typo.
v3: Fixed format issues, clarified a variable name,
changed pr_warn() to DRM_INFO() as suggested by
Jani Nikula <[email protected]>.
