Subject: [PATCH 2/2] drm/i915/snps_hdmi_pll: Use clamp() instead of max(min())
Date: Wed, 18 Jun 2025 18:39:51 +0530	[thread overview]
Message-ID: <20250618130951.1596587-3-ankit.k.nautiyal@intel.com> (raw)
In-Reply-To: <20250618130951.1596587-1-ankit.k.nautiyal@intel.com>

The values of ana_cp_int, and ana_cp_prop are clamped between 1 and 127.
Use the more intuitive and readable clamp() macro instead of using
nested max(min(...)).
