3.2.65-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx> commit b41583e7299046abdc578c33f25ed83ee95b9b31 upstream. In case of 8 bit mode and DMA usage we end up with every second byte written as 0. We have to respect bits_per_word settings what this patch actually does.
