Subject: iser-target: Cast wr_id with uintptr_t instead of unsinged long
X-Git-Tag: v3.19-rc1~12^2~19
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=b0a191e703dfc6a1496a668a2650f8fc9360936d;p=uclinux-h8%2Flinux.git

iser-target: Cast wr_id with uintptr_t instead of unsinged long

Nit, uintptr_t is designed for pointer casting, use it.
