| Subject: IB/iser: Fix dma_nents type definition |
| |
| From: Max Gurtovoy <maxg@mellanox.com> |
| |
| [ Upstream commit c1545f1a200f4adc4ef8dd534bf33e2f1aa22c2f ] |
| |
| 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") |
