Subject: pch_dma: Reduce wasting memory
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=01631243d712d41681d61c0556341a3329860c47;p=linux-beck.git

pch_dma: Reduce wasting memory

nr_channels is defined in "struct pch_dma".
and struct pch_dma_chan is defined in "struct pch_dma".
So, "sizeof(struct pch_dma_chan) * nr_channels" is unnecessary.
