[ Upstream commit 5244ca88671a1981ceec09c5c8809f003e6a62aa ]
The previous build fix left a remaining issue in configurations with 64-bit dma_addr_t on 32-bit architectures:
drivers/infiniband/sw/siw/siw_qp_tx.c: In function 'siw_get_pblpage': drivers/infiniband/sw/siw/siw_qp_tx.c:32:37: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] 32 | return virt_to_page((void *)paddr); | ^
Use the same double cast here that the driver uses elsewhere to convert between dma_addr_t and void*.
