Imre Deak dccf82ad17 drm/i915/gen9: Fix PCODE polling during SAGV disabling ... According to the previous patch, it's possible atm that we call intel_do_sagv_disable() only once during the 1ms period and time out if that call fails. As opposed to this the spec says that we need to keep retrying this request for a 1ms duration, so let's do this similarly to the CDCLK change notification request. v4-5: - Rebased on the reply_mask, reply change. v6: - Remove w/s change. (Lyude) - Rebased on the timeout_base argument change.
