Subject: [PATCH 04/10] spi: meson-spicc: Use FIELD_MODIFY()
Date: Thu, 30 Apr 2026 23:54:50 +0800	[thread overview]
Message-ID: <20260430155456.36998-5-18255117159@163.com> (raw)
In-Reply-To: <20260430155456.36998-1-18255117159@163.com>

Use FIELD_MODIFY() to remove open-coded bit manipulation.
No functional change intended.
