Subject: [PATCH 03/10] drm/i915/vlv: Remove redundant power well ID asserts
Date: Fri, 20 Jul 2018 17:14:57 +0300	[thread overview]
Message-ID: <20180720141504.22832-4-imre.deak@intel.com> (raw)
In-Reply-To: <20180720141504.22832-1-imre.deak@intel.com>

The callbacks these asserts are called from are used from a single power
well, so not much point in checking that. The check also requires a unique
power well ID that we would need to keep around only for this purpose.
(A follow-up patch removes power well IDs not needed for direct power
 well access).
