Subject: [Intel-gfx] [PATCH v2 2/2] drm/i915/hdcp: No direct access to power_well desc
Date: Mon, 18 May 2020 16:48:04 +0530	[thread overview]
Message-ID: <20200518111804.11842-3-anshuman.gupta@intel.com> (raw)
In-Reply-To: <20200518111804.11842-1-anshuman.gupta@intel.com>

HDCP code doesn't require to access power_well internal stuff,
instead it should use the intel_display_power_well_is_enabled()
to get the status of desired power_well.
No functional change.

v2:
- used with_intel_runtime_pm instead of get/put. [Jani]
