Hi all, After merging the usb tree, today's linux-next build (x86_64 allmodconfig) failed like this:
In file included from usr/include/linux/usbdevice_fs.hdrtest.c:1:
./usr/include/linux/usbdevice_fs.h:88:2: error: unknown type name 'u8'
u8 num_ports; /* Number of ports the device is connected */
^~
./usr/include/linux/usbdevice_fs.h:92:2: error: unknown type name 'u8'
u8 ports[7]; /* List of ports on the way from the root */
^~
Caused by commit
6d101f24f1dd ("USB: add usbfs ioctl to retrieve the connection parameters")
Presumably exposed by commit
b91976b7c0e3 ("kbuild: compile-test UAPI headers to ensure they are
self-contained")
from the kbuild tree.
I have added this patch for now:
