Subject: [PATCH] drm/i915: Drop the extra GEN8_PCU_IIR posting read from
 cherryview_irq_preinstall()
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Looks like a leftover POSTING_READ(GEN8_PCU_IIR) in
cherryview_irq_preinstall() from some earlier age. GEN5_IRQ_RESET()
already does the posting read so this changes nothing, so kill it.
