Subject: [PATCH] habanalabs: Add mask for CS type bits in CS flags
Date: Sun, 29 Nov 2020 00:22:04 +0200 [thread overview]
Message-ID: <20201128222207.23722-2-ogabbay@kernel.org> (raw)
In-Reply-To: <20201128222207.23722-1-ogabbay@kernel.org>
From: Tomer Tayar <ttayar@habana.ai>
hl_cs_sanity_checks() extracts the CS type bits of the CS flags, by
masking out the non-type bits.
To save the need for updating the function whenever new bits for
non-type flags are added, add an explicit mask for the CS type bits.
