evaluation order bug in acpi_pic_sci_set_trigger() ?

[Alexey Dobriyan <adobriyan@xxxxxxxxx>]

acpi_pic_sci_set_trigger() contains the following code:

	/* Real old ELCR mask */
	old = inb(0x4d0) | (inb(0x4d1) << 8);

Operand evalution order is not guaranteed for binary or.
I wonder if this is a bug?
