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.
