Subject: [PATCH AUTOSEL 6.1 5/5] dmaengine: fsl-qdma: increase size of 'irq_name'
Date: Mon, 29 Jan 2024 13:35:57 -0500 [thread overview]
Message-ID: <20240129183559.464502-5-sashal@kernel.org> (raw)
In-Reply-To: <20240129183559.464502-1-sashal@kernel.org>
From: Vinod Koul <vkoul@kernel.org>
[ Upstream commit 6386f6c995b3ab91c72cfb76e4465553c555a8da ]
We seem to have hit warnings of 'output may be truncated' which is fixed
by increasing the size of 'irq_name'
drivers/dma/fsl-qdma.c: In function ‘fsl_qdma_irq_init’:
drivers/dma/fsl-qdma.c:824:46: error: ‘%d’ directive writing between 1 and 11 bytes into a region of size 10 [-Werror=format-overflow=]
824 | sprintf(irq_name, "qdma-queue%d", i);
| ^~
drivers/dma/fsl-qdma.c:824:35: note: directive argument in the range [-2147483641, 2147483646]
824 | sprintf(irq_name, "qdma-queue%d", i);
| ^~~~~~~~~~~~~~
drivers/dma/fsl-qdma.c:824:17: note: ‘sprintf’ output between 12 and 22 bytes into a destination of size 20
824 | sprintf(irq_name, "qdma-queue%d", i);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
