Subject: [PATCH v3 1/5] spi: dw: use DW_SPI_ISR directly
Date: Wed, 9 Sep 2026 22:36:48 +0800 [thread overview]
Message-ID: <20260909143652.9234-2-jszhang@kernel.org> (raw)
In-Reply-To: <20260909143652.9234-1-jszhang@kernel.org>
The DW_SPI_ISR register reports the masked interrupts, no need to mask
again.
