Subject: [PATCH 14/15] habanalabs: add warning print upon a PCI error
Date: Thu, 27 Oct 2022 12:10:06 +0300 [thread overview]
Message-ID: <20221027091007.664797-14-ogabbay@kernel.org> (raw)
In-Reply-To: <20221027091007.664797-1-ogabbay@kernel.org>
From: Ofir Bitton <obitton@habana.ai>
In order to know if driver catches PCI errors correctly, we need to
print a warning per each error.
