484919cf33 fsl_dma: Fix Channel Start bug in dma_check()
The Channel Start (CS) bit in the Mode Register (MR) should actually be
cleared as the comment in the code suggests.  Previously, CS was being
set, not cleared.

Assuming normal operation of the DMA engine, this change shouldn't have
any real affect.

53677ef18e Big white-space cleanup.
This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

fails
