Subject: [Intel-gfx] [CI 2/4] drm/i915/dmc: Change intel_get_stepping_info()
Date: Wed, 21 Jul 2021 14:52:36 -0700	[thread overview]
Message-ID: <20210721215238.24980-2-anusha.srivatsa@intel.com> (raw)
In-Reply-To: <20210721215238.24980-1-anusha.srivatsa@intel.com>

Lets use RUNTIME_INFO->step since all platforms now have their
stepping info in intel_step.c. This makes intel_get_stepping_info()
a lot simpler.
