From dd5d81f326da8d151939b833993b799c0d0d1d6e Mon Sep 17 00:00:00 2001 From: Renzo Davoli Date: Wed, 23 Sep 2009 15:57:10 -0700 Subject: 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.
