Subject[PATCH 08/10] ACPICA: Hardware: Cast GPE enable_mask before storing
Date
From: "David E. Box" <david.e.box@linux.intel.com>

ACPICA commit 490ec7f7839bf7ee5e8710a34d1d1a78d54a49b6

In function acpi_hw_low_set_gpe(), cast enable_mask to u8 before
storing. The mask was read from a 32 bit register but is an 8 bit
value. Fixes Visual Studio compiler warning.
