usb-storage: Use const to reduce object data size
Make structs const to reduce data size ~20KB. Change function arguments and prototypes as necessary to compile. $ size (x86-64 defconfig pre) text data bss dec hex filename 12281 10948 480 23709 5c9d ./drivers/usb/storage/usb.o 111 10528 8 10647 2997 ./drivers/usb/storage/usual-tables.o $ size (x86-64 defconfig post) text data bss dec hex filename 22809 420 480 23709 5c9d drivers/usb/storage/usb.o 10551 0 0 10551 2937 drivers/usb/storage/usual-tables.o Signed-off-by: Joe Perches <joe@perches.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Link: https://lore.kernel.org/r/cf13bd2d790ae3afbf5da55ea7bed12e00c5119d.camel@perches.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
