From: Arnd Bergmann Date: Wed, 7 Oct 2015 12:29:51 +0000 (+0200) Subject: IB/core: avoid 32-bit warning X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=5d1e623591dfaa64a59ecdac420adc16125524d4;p=openwrt%2Fstaging%2Fblogic.git 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.
