Can you try:
diff --git a/drivers/gpu/drm/i915/intel_i2c.c b/drivers/gpu/drm/i915/intel_i2c.c index 58040f6..111128d 100644 --- a/drivers/gpu/drm/i915/intel_i2c.c +++ b/drivers/gpu/drm/i915/intel_i2c.c @@ -384,7 +384,7 @@ int intel_setup_gmbus(struct drm_device *dev) bus->reg0 = i | GMBUS_RATE_100KHZ; /* XXX force bit banging until GMBUS is fully debugged */ - bus->force_bit = intel_gpio_create(dev_priv, i); + //bus->force_bit = intel_gpio_create(dev_priv, i); } intel_i2c_reset(dev_priv->dev); -Chris -- Chris Wilson, Intel Open Source Technology Centre
