[ Upstream commit 3522f867c13b63cf62acdf1b8ca5664c549a716a ]

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.
