+Subject: [PATCH] serial: RS485 ioctl structure uses __u32 include linux/types.h
+MIME-Version: 1.0

+In the commit below a new struct serial_rs485 was introduced for a new
+ioctl:

+
+ tty: Cris has a nice RS485 ioctl so we should steal it
+
+This structure uses the __u32 types for some of its members, which leads
+to the following compile error:
+
+ $ cc -I.../include -c X.c
+ In file included from X.c:2: .../include/linux/serial.h:185:
+ error: expected specifier-qualifier-list before ‘__u32’
+ $
+
+It seems that these types are appropriate for this structure as it is
+to be exposed to userspace. These types are available via linux/types.h
+so move the include of that outside the __KERNEL__ section.
