Date: Fri, 11 Nov 2011 08:37:40 +0000 [thread overview]
Message-ID: <20111111083740.3e02c46a@bob.linux.org.uk> (raw)
In-Reply-To: <1320976527-6142-1-git-send-email-tomoya.rohm@gmail.com>
> MODIFICATION:
> Currently, when release DMA channel resource, this driver checks
> dma-flag. However, this specification occurs the above issue.
> This driver must check whether dma_request_channel is executed or
> not. The values are saved in private data variable "chan_tx/chan_tx".
> These variables mean if the value is NULL, DMA channel is not
> requested, if not NULL, DMA channel is requested.
>
> This patch fixes the issue.
