Subject: [PATCH 1/2] habanalabs: rate limit multi CS completion errors
Date: Mon, 13 Sep 2021 22:11:45 +0300 [thread overview]
Message-ID: <20210913191146.92956-1-ogabbay@kernel.org> (raw)
From: Ofir Bitton <obitton@habana.ai>
As user can send wrong arguments to multi CS API, we rate limit
the amount of errors dumped to dmesg, in addition we change the
severity to warning.
