I don't think so, since gpio is reserving it as a core_initcall() it
gets a high chardev major. It's likely the device that used to
be device 232 stealing the fingerprint sensor slot that got
pushed down and is now stealing device 231 infiniband.
Maybe I should make a patch making fs/char_dev.c emit a warning
or fail when it goes below 234... it doesn't currently. It just steals
more numbers. It's a serious archtectural issue if it persists.
