ASoC: davinci-pcm: trivial: make ping-pong params setup symmetrical
Browse files Browse the repository at this point in the history
The setup of the pong channel uses EDMA_CHAN_SLOT instead of & 0x3f as the
setup of the ping channel does.

Make the setup of ping and pong symmetric. There is no functional change
introduced by this patch.
