From 7693f5d39ee0134b1398a57c2998a0b67ef56700 Mon Sep 17 00:00:00 2001 From: Oded Gabbay Date: Thu, 29 Apr 2021 16:50:05 +0300 Subject: [PATCH] habanalabs: ignore device unusable status Some users might want to implement their own policy of when the device is unusable so we need to ignore this status in the driver and continue loading as normal.
