Hi Anand and folks,

Since the merging of linux-omap tree with linus tree, I'm facing a problem with MMC multislot support on N800 boards, that stops working. 

Well, after investigating recent modifications on DMA, I was verifying Anand Gadiyar' patch 'OMAP: DMA: Added support for DMA chaining' and I realize a line of this patch is the source of the problem.

Apparently, the attribution 

+       status = OMAP_DMA_CSR_REG(ch);

is necessary only if the ch is not chained.

Tested on N800 with MMC multislot support and works fine again.

BR,

Carlos.
