Subject: [PATCH 5.12 002/178] dmaengine: idxd: add missing dsa driver unregister

From: Dave Jiang <dave.jiang@...el.com>

[ Upstream commit 077cdb355b3d8ee0f258856962e6dac06e744401 ]

The idxd_unregister_driver() has never been called for the idxd driver upon
removal. Add fix to call unregister driver on module removal.

Fixes: c52ca478233c ("dmaengine: idxd: add configuration component of driver")
