Subject: [PATCH 1/2] habanalabs: failure to open device due to reset is debug level
Date: Mon, 19 Sep 2022 15:10:24 +0300	[thread overview]
Message-ID: <20220919121025.58172-1-ogabbay@kernel.org> (raw)

If the user wants to open the device, and the device is currently in
reset, the user will get an error from the open().

We don't need to display an error in the dmesg for that as it is
not a real error and we can spam the kernel log with this message.
