[PATCH 02/03] fbdev: maxine: elide an unused function

[Randy Dunlap]

maxinefb_ims332_read_register() is not used, but since it describes a
hardware interface, leave it in the source file as documentation
and surround it inside an #if 0/#endif block.

../drivers/video/fbdev/maxinefb.c:74:21: warning: 'maxinefb_ims332_read_register' defined but not used [-Wunused-function]
   74 | static unsigned int maxinefb_ims332_read_register(int regno)
