From 60e95f43fc8573e81f54b0c1e0bc542c2260d956 Mon Sep 17 00:00:00 2001 From: Linda Knippers Date: Wed, 22 Jul 2015 16:17:22 -0400 Subject: [PATCH] nfit: Don't check _STA on NVDIMM devices The _STA only applies to the root device, not the individual NVDIMMS, so don't check here. NVDIMM device state flags are checked elsewhere.
