Thanks Greg.

Keerthimai, a possibly "better" fix would be to add a
do { ... } while (0) guard and semicolons to the relatively
ugly US_DO_ALL_FLAGS macro and US_FLAG uses in
include/linux/usb_usual.h

include/linux/usb_usual.h:#define US_DO_ALL_FLAGS                                               \
include/linux/usb_usual.h-      US_FLAG(SINGLE_LUN,     0x00000001)                     \
include/linux/usb_usual.h-              /* allow access to only LUN 0 */                \
include/linux/usb_usual.h-      US_FLAG(NEED_OVERRIDE,  0x00000002)                     \
include/linux/usb_usual.h-              /* unusual_devs entry is necessary */           \
...

and then add a semicolon to the uses of US_DO_ALL_FLAGS
and then remove a semicolon as above.
