Subject: [PATCH] RDMA/cxgb4: re-fix 32-bit build warning
Date: Wed, 07 Oct 2015 14:10:04 +0200 [thread overview]
Message-ID: <13543971.LQ3Q8CCxhL@wuerfel> (raw)
Casting a pointer to __be64 produces a warning on 32-bit architectures:
drivers/infiniband/hw/cxgb4/mem.c:147:20: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
req->wr.wr_lo = (__force __be64)&wr_wait;
This was fixed at least twice for this driver in different places,
and accidentally reverted once more. This puts the correct version
back in place.

Fixes: 6198dd8d7a6a7 ("iw_cxgb4: 32b platform fixes")
