Subject: [PATCH 4/7] drm/i915/pmu: Drop is_igp()
Date: Mon, 22 Jul 2024 14:06:45 -0700	[thread overview]
Message-ID: <20240722210648.80892-5-lucas.demarchi@intel.com> (raw)
In-Reply-To: <20240722210648.80892-1-lucas.demarchi@intel.com>
There's no reason to hardcode checking for integrated graphics on a
specific pci slot. That information is already available per platform an
can be checked with IS_DGFX().
