Subject: ARM: OMAP: Fix chain_a_transfer return value
X-Git-Tag: v2.6.25-rc7~59^2^2~2
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=f4b6a7ef6c64d84e252d32df631813bd09ea3756;p=linux-2.6-omap-h63xx.git

ARM: OMAP: Fix chain_a_transfer return value

This patch changes the return value of omap_dma_chain_a_transfer
to 0 on success instead of the flag 'start_dma', which wasn't really useful
for anything.
