Subject: [Intel-wired-lan] [PATCH v4 05/15] ice: use designated initializers for TSPLL consts
Date: Thu, 01 May 2025 15:54:16 -0700 [thread overview]
Message-ID: <20250501-kk-tspll-improvements-alignment-v4-5-24c83d0ce7a8@intel.com> (raw)
In-Reply-To: <20250501-kk-tspll-improvements-alignment-v4-0-24c83d0ce7a8@intel.com>
From: Karol Kolacinski <karol.kolacinski@intel.com>
Instead of multiple comments, use designated initializers for TSPLL
consts.
Adjust ice_tspll_params_e82x fields sizes.
