Subject: [PATCH] drm/imx/dcss: add missing kernel-doc parameters for scaler functions

From: Rosen Penev <[email-masked]>
Date: Sat, 30 May 2026 12:59:25 -0700

dcss_scaler_gaussian_filter() was missing @phase0_identity and
dcss_scaler_filter_design() was missing @phase0_identity and
@nn_interpolation in their kernel-doc comments.
