fs/char_dev.c: remove useless loop
There are two useless lines in fs/char_dev.c.
In register_chrdev there is a loop to change all '/' into '!' in the
kernel object name.
This code is useless as the same substitution is in kobject_set_name_vargs in
lib/kobject.c:
228 /* ewww... some of these buggers have '/' in the name ... */
229 while ((s = strchr(kobj->name, '/')))
230 s[0] = '!';
kobject_set_name_vargs is called by kobject_set_name.
kobject_set_name is called just above the useless loop.
