Subject: [PATCH v2 1/4] pinctrl: intel: refine set_mux hook
Date:   Fri,  9 Jun 2023 13:55:36 +0530
Message-Id: <20230609082539.24311-2-raag.jadav@intel.com>
In-Reply-To: <20230609082539.24311-1-raag.jadav@intel.com>
References: <20230609082539.24311-1-raag.jadav@intel.com>
Precedence: bulk

Utilize a temporary variable for common shift operation
inside ->set_mux() hook and improve readability.
