[WATCHDOG] iTCO_wdt.c - fix ACPI Base register
The ACPI/PM base I/O address which is the base for the TCO registers is defined as bits [15:7] (highest bit is 31, lowest is 0) The code however only reads bits [14:7]. So base_address &= 0x00007f80; needs to be: base_address &= 0x0000ff80; This patch fixes this. Signed-off-by: Ate Wijma <ajwijma@hotmail.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
