[Gnewsense-dev] [loongson-PATCH-v1 03/27] fix-error: incompatiable argument type of clear_user

[wuzhangjin]

From: Wu Zhangjin <address@hidden>

there are lots of warnings about the macro: clear_user in linux-mips.

the type of the second argument of access_ok should be (void __user *),
but there is an un-needed (unsigned long) conversion before __cl_addr,
so, remove the (unsigned long) will fix this problem.
