cris: gpio: do not call copy_to_user()/copy_from_user() while holding spinlocks

From: Miklos Szeredi <mszeredi(a)suse.cz> In the old times pseudo-filesystems set the name of theroot dentry to some prefix like "pipe:" and the name of the child dentry to "[123]" and relied on a hack in __d_path() to replace the preceding slash with the root's name to get "pipe:[123]". Then the d_dname() dentr... 2 Aug 2010 08:08
