Subject: Re: [PATCH 4/8] 3w-sas: fix calls to dma_set_mask_and_coherent()
Date: Mon, 25 Feb 2019 19:32:26 -0500 (EST) [thread overview]
Message-ID: <1659665098.3869910.1551141146893.JavaMail.zimbra@redhat.com> (raw)
In-Reply-To: <20190218073426.111853-5-hare@suse.de>
The change to use dma_set_mask_and_coherent() incorrectly made a second
call with the 32 bit DMA mask value when the call with the 64 bit DMA
mask value succeeded.
Fixes: 3a21986f1a59 ("scsi: aic94xx: fully convert to the generic DMA API")
Cc: <stable@vger.kernel.org>
Signed-off-by: Hannes Reinecke <hare@suse.com>

The patch subject should be "aic94xx:", Martin, can you fix this up?
