From: Laine Walker-Avina <laine.walker-avina@intel.com> mainline inclusion from mainline-5.2-rc2 commit 2d466c7a574d0b893a233735f133c60115013c0e category: bugfix bugzilla: 167363 CVE: NA --------------------------- We use the controller's reported maximum firmware activation time as our timeout before resetting a controller for a failed activation notice, but this value was never being read so we could only use the default timeout. Copy the Identify Controller MTFA field to the corresponding nvme_ctrl's mtfa field. Fixes: b6dccf7fae433 (“nvme: add support for FW activation without reset”).
