<pre>commit e29cc1d7e820d662d2d73b35281b70f01a24610b

drm/i915/guc: reorder enable/disable communication steps
Make sure we always have CT buffers enabled when the interrupts are
enabled, so we can always handle interrupts from GuC. Also move the
setting of the guc->send and guc->handler functions to the GuC
communication control functions for consistency.
The reorder also fixes the onion unwinding of intel_uc_init_hw, because
guc_enable_communication would've left interrupts enabled when failing
to enable CTB.
v2: always retunr the result of ctch_enable() in
intel_guc_ct_enable() (Michal)
