Subject: [PATCH v5 14/24] drm/xe: Simplify madvise_preferred_mem_loc()
Date: Thu, 18 Dec 2025 17:20:51 +0100	[thread overview]
Message-ID: <20251218162101.605379-15-thomas.hellstrom@linux.intel.com> (raw)
In-Reply-To: <20251218162101.605379-1-thomas.hellstrom@linux.intel.com>

Simplify madvise_preferred_mem_loc by removing repetitive patterns
in favour of local variables.
