Revision 6045dd7e5955f0175c9075f8ba80015369d6b201 authored by Rikard Falkeborn on 08 May 2020, 21:44:21 UTC, committed by Felipe Balbi on 14 May 2020, 09:42:53 UTC
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>
