From 551402a30efa45560e23c22a7aa04453861602c3 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 6 Sep 2010 23:53:47 +0100 Subject: [PATCH] drm: Fix regression in disable polling e58f637 I broke out my trusty i845 and found a new boot failure, which upon inspection turned out to be a recursion within: drm_helper_probe_single_connector_modes() -> drm_helper_hpd_irq_event() -> intel_crt_detect() -> drm_helper_probe_single_connector_modes() Calling drm_kms_helper_poll_enable() instead performs the desired re-initialisation of the polling should the user have toggled the parameter, without the recursive side-effect.
