Subject: [PATCH] ACPI: EC: Fix debugfs_create_*() usage
Git-commit: 3522f867c13b63cf62acdf1b8ca5664c549a716a
Patch-mainline: v4.16-rc1
References: bsc#1051510

acpi_ec.gpe is "unsigned long", hence treating it as "u32" would expose
the wrong half on big-endian 64-bit systems.  Fix this by changing its
type to "u32" and removing the cast, as all other code already uses u32
or sometimes even only u8.
