Subject: [PATCH 02/22] ncr5380: Remove FLAG_NO_PSEUDO_DMA where possible
Date: Mon, 14 Mar 2016 15:27:02 +1100 [thread overview]
Message-ID: <20160314042701.115991238@telegraphics.com.au> (raw)
In-Reply-To: 20160314042700.596192247@telegraphics.com.au
[-- Attachment #1: ncr5380-FLAG_NO_PSEUDO_DMA --]
[-- Type: text/plain, Size: 4073 bytes --]
Drivers that define PSEUDO_DMA also define NCR5380_dma_xfer_len.
The core driver must call NCR5380_dma_xfer_len which means
FLAG_NO_PSEUDO_DMA can be eradicated from the core driver.
dmx3191d doesn't define PSEUDO_DMA and has no use for FLAG_NO_PSEUDO_DMA,
so remove it there also.
