Subject: mmp_tdma: set cookies as well when asked for tx status
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c14d2bc4709e8d5102a71f222fdd5a2b0c14c669;p=linux-beck.git

mmp_tdma: set cookies as well when asked for tx status

dma_set_residue() sets only residue value, so user can't rely on the returned
values of cookies. That patch standardize the behaviour.
