[PATCH 5/5] staging: ccree: dma mask is type u64

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

 



The dma mask var was defined as dma_addr_t but should be
u64. This showed as a sparse warning when building for 32 bit.
Fix it by changing type to u64 and drop the cast.
