[PATCH 5.12 001/178] dmaengine: idxd: add engine struct device missing bus type assignment

[Greg Kroah-Hartman]

From: Dave Jiang <dave.jiang@xxxxxxxxx>

[ Upstream commit 1c4841ccbd2b185587010d6178aac11953f61d4c ]

engine 'struct device' setup is missing assigning the bus type. Add it to
dsa_bus_type.
