    drm/i915: Set HDMI hot plug interrupt enable for only the output in question. · 9d2949a4
    Ma Ling authored
    We detect HDMI output connection status by writing to HOT Plug Interrupt
    Detect Enable bit in PORT_HOTPLUG_EN.  The behavior will generate a specified
    interrupt, which is caught by audio driver, but during one detection driver
    set all Detect Enable bits of HDMIB, HDMIC HDMID, and generate wrong
    interrupt signals for current output, according to the signals audio driver
    misunderstand device status. The patch intends to handle corresponding
    output precisely.
