Subject: [PATCH] dmaengine: idxd: set DMA_INTERRUPT cap bit
Git-commit: 4e5a4eb20393b851590b4465f1197a8041c2076b
Patch-mainline: v5.19-rc1
References: git-fixes
Even though idxd driver has always supported interrupt, it never actually
set the DMA_INTERRUPT cap bit. Rectify this mistake so the interrupt
capability is advertised.
