[PATCH] crypto: chelsio - Fix an error code in chcr_hash_dma_map()

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

 



The dma_map_sg() function returns zero on error and positive values on
success.  We want to return -ENOMEM on failure here and zero on success.

Fixes: 2f47d5804311 ("crypto: chelsio - Move DMA un/mapping to chcr from lld cxgb4 driver")
