Subject: [PATCH 06/11] drm/vkms: rename struct vkms_color_lut::base to y
Date: Tue,  4 Aug 2026 17:33:46 -0300	[thread overview]
Message-ID: <20260804203351.148521-7-leandro.ribeiro@collabora.com> (raw)
In-Reply-To: <20260804203351.148521-1-leandro.ribeiro@collabora.com>

No behavior change. In the following commits we'll add x, so y better
matches that.
