From: Arnd Bergmann <a...@arndb.de> struct ucan_message_in contains member with 4-byte alignment but is itself marked as unaligned, which triggers a warning:
drivers/net/can/usb/ucan.c:249:1: warning: alignment 1 of 'struct ucan_message_in' is less than 4 [-Wpacked-not-aligned] Mark the outer structure to have the same alignment as the inner one.
