Subject: media: em28xx: constify most static structs
Author: Mauro Carvalho Chehab <mche...@s-opensource.com>
Date: Thu Mar 1 10:34:34 2018 -0500
There are several em28xx static structs that can now be constified.
That caused a significant reduction at data segment:
Before:
text data bss dec hex filename
85017 59588 576 145181 2371d drivers/media/usb/em28xx/em28xx.o
After:
text data bss dec hex filename
112345 32292 576 145213 2373d drivers/media/usb/em28xx/em28xx.o
