Dave Jiang e5eb9757fe dmaengine: idxd: fix wq cleanup of WQCFG registers ... [ Upstream commit ea9aadc06a ] A pre-release silicon erratum workaround where wq reset does not clear WQCFG registers was leaked into upstream code. Use wq reset command instead of blasting the MMIO region. This also address an issue where we clobber registers in future devices.
