From a6b07e89fd8530b943217ccd4909d1bf65acc45d Mon Sep 17 00:00:00 2001 From: Luc Van Oostenryck Date: Mon, 9 Dec 2019 22:37:19 +0100 Subject: [PATCH] misc: xilinx_sdfec: add missing __user annotation The second arg of xsdfec_set_order() is a 'void __user *' and this pointer is then used in get_user() which expect a __user pointer. But get_user() can't be used with a void pointer, it a pointer to the effective type. This is done here by casting the argument to a pointer to the effective type but the __user is missing in the cast. Fix this by adding the missing __user in the cast.
