This code elsewhere returns a negative constant to an indicate an error,
while IS_ERR returns the result of a >= operation.

The semantic patch that fixes this problem is as follows:

 if (...) { ...

Convert DMA library into DMA platform driver and make use of
platform data provided by hwmod data base for OMAP2+ onwards.

For OMAP1 processors, the DMA driver in mach-omap uses resource
structures for getting platform data.

Thanks to Tony Lindgren <tony@atomide.com> for fixing various
omap1 issues and testing the same on OSK5912 board.
