From 2eea65829dc6c20dccbe79726fd0f3fe7f8aa43b Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Mon, 2 May 2016 09:11:53 -0700 Subject: [PATCH] nfit: fix translation of command status results When transportation of the command completes successfully, it indicates that the 'status' result is valid. Fix the missed checking and translation of the status field at the end of acpi_nfit_ctl(). Otherwise, we fail to handle reported errors and assume commands complete successfully.
