From 957b247bca4309b07df991ce114ea7a617b2c9fb Mon Sep 17 00:00:00 2001 From: Tal Cohen Date: Thu, 16 Mar 2023 17:30:46 +0200 Subject: [PATCH] accel/habanalabs: print event type when device is disabled When the device is in disabled state, the driver isn't suppose to receive any events from FW. Printing the event type, as part of the message that was already printed, shall help to get more info if this unexpected message is received.
