Subject: [PATCH] dmaengine: idxd: match type for retries var in idxd_enqcmds()
Git-commit: 5d9d16e5aa0cf023e600bf716239fd9caa2d4148
Patch-mainline: v5.18-rc4
References: git-fixes

wq->enqcmds_retries is defined as unsigned int. However, retries on the
stack is defined as int. Change retries to unsigned int to compare the same
type.
