Subject: USB: musb: do not override DMA mode in channel program
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8ca47c8a7621835914c053caaec74e66147dd7dc;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

USB: musb: do not override DMA mode in channel program

There is no reason for the DMA channel program to override the
DMA mode passed down by its caller. Use the passed parameter
directly, and let the caller handle the decision on which mode
is to be used.
