Subject: dmaengine/dw_dmac: Don't use magic number for total number of channels
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e8d9f875c9b02bb56ba3bb44834ae81ba0e8efbc;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

dmaengine/dw_dmac: Don't use magic number for total number of channels

Total number of channels is passed in pdata->nr_channels variable, thus we must
not use magic number '7' for total number of channels.
