Subject: [PATCH v3 05/14] drm/tidss: dispc: Get rid of FLD_GET
Date: Wed, 27 Aug 2025 17:12:36 +0200	[thread overview]
Message-ID: <20250827-drm-tidss-field-api-v3-5-7689b664cc63@kernel.org> (raw)
In-Reply-To: <20250827-drm-tidss-field-api-v3-0-7689b664cc63@kernel.org>

The FLD_GET function is an equivalent to what FIELD_GET + GENMASK
provide, so let's drop it and switch to the latter.
