commit 81df2d594340dcb6d1a02191976be88a1ca8120c ("USB: allow match
on bInterfaceNumber") added a byte to the interior of struct usb_device_id,
enabling implicit padding:
--- a/include/linux/mod_devicetable.h
+++ b/include/linux/mod_devicetable.h
@@ -115,6 +118,9 @@ struct usb_device_id {
__u8 bInterfaceSubClass;
__u8 bInterfaceProtocol;
+ /* Used for vendor-specific interface matches */
+ __u8 bInterfaceNumber;
+
/* not matched against */
kernel_ulong_t driver_info;
};
On m68k, this causes failures like:
| FATAL: drivers/gpu/drm/udl/udl: sizeof(struct usb_device_id)=24 is
not a modulo of the size of section __mod_usb_device_table=44.
| Fix definition of struct usb_device_id in mod_devicetable.h
M68k is special in that it uses 2 for the alignment of 32-bit entities, hence
sizeof(struct usb_device_id) = 22.
However, when cross-compiling on amd64, sizeof(struct usb_device_id) = 24
in scripts/mod/file2alias.c.
