From: Gavin Shan Date: Tue, 23 Jun 2015 07:01:13 +0000 (+1000) Subject: powerpc/powernv: Unfreeze VF PE on releasing it X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f951e51003860705fc9fc663fbce90f8263a6804;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git powerpc/powernv: Unfreeze VF PE on releasing it When releasing PE for SRIOV VF, the PE is forced to be frozen wrongly. When the same PE is picked for another VF, it won't work anyhow. The patch fixes the issue by unfreezing, not freezing the VF PE when releasing it.
