Message-ID: <17269152.DqJfCm1LOx@wuerfel> Date: Wed, 07 Oct 2015 14:29:51 +0200 From: Arnd Bergmann <arnd@...db.de> To: Doug Ledford <dledford@...hat.com>, Sean Hefty <sean.hefty@...el.com>, Hal Rosenstock <hal.rosenstock@...il.com> Cc: Roland Dreier <roland@...estorage.com>, linux-rdma@...r.kernel.org, Matan Barak <matanb@...lanox.com>, Or Gerlitz <ogerlitz@...lanox.com>, linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org Subject: [PATCH] IB/core: avoid 32-bit warning The INIT_UDATA() macro requires a pointer or unsigned long argument for both input and output buffer, and all callers had a cast from when the code was merged until a recent restructuring, so now we get core/uverbs_cmd.c: In function 'ib_uverbs_create_cq': core/uverbs_cmd.c:1481:66: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] This makes the code behave as before by adding back the cast to unsigned long.
