Date: Mon, 10 Mar 2014 16:34:51 -0500 From: Peter Tyser <ptyser@...-inc.com> To: linux-kernel@...r.kernel.org Cc: Peter Tyser <ptyser@...-inc.com>, Guenter Roeck <linux@...ck-us.net>, James Ralston <james.d.ralston@...el.com>, Samuel Ortiz <sameo@...ux.intel.com>, Lee Jones <lee.jones@...aro.org> Subject: [PATCH 1/8] mfd: lpc_ich: Fix ACPI enable bitmask The original bitmask of 0x10 was incorrect and would result in a write to a reserved read-only bit instead of enabling the ACPI I/O region. Update it to the proper value of 0x80.
