From d0ad42388a396813771e9407614f40d128ad62db Mon Sep 17 00:00:00 2001 From: Dave Jiang Date: Thu, 5 May 2022 08:05:07 -0700 Subject: [PATCH] dmaengine: idxd: skip irq free when wq type is not kernel Skip wq irq resources freeing when wq type is not kernel since the driver skips the irq alloction during wq enable. Add check in wq type check in idxd_wq_free_irq() to mirror idxd_wq_request_irq().
