Subject: [PATCH] dmaengine: idxd: set DMA_INTERRUPT cap bit
Date: Mon, 11 Apr 2022 15:09:38 -0700	[thread overview]
Message-ID: <164971497859.2201379.17925303210723708961.stgit@djiang5-desk3.ch.intel.com> (raw)

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.
