[PATCH] remove MOD_IN_USE
Another left-over from ancient module code, it was supposed to return
non-zero if the module has a use count, but currently it always
evaluates to 0.
There are a few users of different types:
(1) ioctl that perform a while(MOD_IN_USE) MOD_DEC_USE_COUNT loop.
Just rip them out, we now have forced module unloading.
(2) printk's that moan if the use-count in not zero in the exitfunc.
Just rip them out, this can't happen.
(3) if(MOD_IN_USE) MOD_DEC_USE_COUNT constructs in ->close of a few
serial drivers. Just remove the conditional, we did a
MOD_INC_USE_COUNT in ->open.
(4) This one is interesting: drivers/sbus/char/display7seg.c uses
the module use count to track openers. Replace this with an
atomic_t.
In addition remove tons of stale comments in network driver that aren't
understandable for anyone who doesn't know ancient Linux module semantics.
