X-Git-Tag: v4.9.121~14
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cc83ba490ddae49dc2c8ccdf2f32ae2ac4aeb562;p=platform%2Fkernel%2Flinux-amlogic.git

x86: i8259: Add missing include file

commit 0a957467c5fd46142bc9c52758ffc552d4c5e2f7 upstream.

i8259.h uses inb/outb and thus needs to include asm/io.h to avoid the
following build error, as seen with x86_64:defconfig and CONFIG_SMP=n.
