Subject[PATCH] RDMA/cxgb4: silence GCC warning
From
Date
Building mem.o for 32 bits x86 triggers a GCC warning:
drivers/infiniband/hw/cxgb4/mem.c: In function '_c4iw_write_mem_dma_aligned':
drivers/infiniband/hw/cxgb4/mem.c:79:25: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]

Silence that warning by casting "&wr_wait" to unsigned long before
casting it to __be64. That's what _c4iw_write_mem_inline() already does.

0) Compile tested only (on 32 bit x86): I do not have this hardware.

1) This warning was introduced in v3.10-rc1, through commit 42b6a949903d
("RDMA/cxgb4: Use DSGLs for fastreg and adapter memory writes for T5.").
