Subject: [PATCH 3/5] spi: dw: use DW_SPI_ISR directly
Date: Mon, 15 Jun 2026 12:40:37 +0800 [thread overview]
Message-ID: <20260615044039.9750-4-jszhang@kernel.org> (raw)
In-Reply-To: <20260615044039.9750-1-jszhang@kernel.org>
The DW_SPI_ISR register reports the masked interrupts, no need to mask
again.
