Subject: x86: i8259: Add missing include file
|
|
|
|
From: Guenter Roeck <linux@roeck-us.net>
|
|
|
|
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.
|
|
