Subject: [PATCH 1/1] IB/iser: Fix dma_nents type definition
Git-commit: c1545f1a200f4adc4ef8dd534bf33e2f1aa22c2f
Patch-mainline: v5.1
References: bsc#1111666
The retured value from ib_dma_map_sg saved in dma_nents variable. To avoid
future mismatch between types, define dma_nents as an integer instead of
unsigned.
Fixes: 57b26497fabe ("IB/iser: Pass the correct number of entries for dma mapped SGL")
