From mboxrd@z Thu Jan 1 00:00:00 1970 From: maxime.ripard@free-electrons.com (Maxime Ripard) Date: Thu, 16 Oct 2014 11:01:00 +0200 Subject: [PATCH 08/11] dmaengine: sa11x0: Remove chancnt affectations In-Reply-To: <1413450063-23829-1-git-send-email-maxime.ripard@free-electrons.com> References: <1413450063-23829-1-git-send-email-maxime.ripard@free-electrons.com> Message-ID: <1413450063-23829-9-git-send-email-maxime.ripard@free-electrons.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org chanctnt is already filled by dma_async_device_register, which uses the channel list to know how much channels there is. Since it's already filled, we can safely remove it from the drivers' probe function.
