Subject: [PATCH] <linux/uaccess.h>: Fix copy_in_user() declaration
Git-commit: f58e76c1c551c7577b25a6fe493d82f5214331b7
Patch-mainline: v4.14-rc1
References: bsc#1052766

copy_in_user() copies data from user-space address @from to user-
space address @to. Hence declare both @from and @to as user-space
pointers.

Fixes: commit d597580d3737 ("generic ...copy_..._user primitives")
