[PATCH AUTOSEL 5.15 3/3] dmaengine: fsl-qdma: increase size of 'irq_name'

[Sasha Levin]

From: Vinod Koul <vkoul@xxxxxxxxxx>

[ 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);
      |                                              ^~
