usb: mtu3: constify struct debugfs_reg32
mtu3_prb_regs is never changed and can therefore be made const. This allows the compiler to put it in the text section instead of the data section. Before: text data bss dec hex filename 19966 7120 0 27086 69ce drivers/usb/mtu3/mtu3_debugfs.o After: text data bss dec hex filename 20142 6992 0 27134 69fe drivers/usb/mtu3/mtu3_debugfs.o Signed-off-by: Rikard Falkeborn <rikard.falkeborn@gmail.com> Signed-off-by: Felipe Balbi <balbi@kernel.org>
