Subject: [PATCH v1 3/8] i2c: bcm-kona: Use i2c_10bit_addr_from_msg() helper
Date: Wed, 12 Feb 2025 18:32:28 +0200 [thread overview]
Message-ID: <20250212163359.2407327-4-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20250212163359.2407327-1-andriy.shevchenko@linux.intel.com>
Use i2c_10bit_addr_from_msg() helper instead of local copy.
No functional change intended.
