Subject: [PATCH 5.10 006/103] dmaengine: idxd: fix delta_rec and crc size field for completion record

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

[ Upstream commit 4ac823e9cd85f66da274c951d21bf9f6b714b729 ]

The delta_rec_size and crc_val in the completion record should
be 32bits and not 16bits.

Fixes: bfe1d56091c1 ("dmaengine: idxd: Init and probe for Intel data accelerators")
