[PATCH 2/7] staging: mt7621-mmc: set correct dma mask.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since commit f8c55dc6e828 ("MIPS: use generic dma noncoherent ops for
simple noncoherent platforms") changed MIPS dma handling, the mmc
driver fails because it doesn't have a dma mask is set.

So set the correct dma mask.
