staging: dgrp: prefix function names with dgrp_ in dgrp_specproc.c
Prefix the functions in dgrp_specproc.c to avoid ambiguity in backtraces, such as the "info_proc_open" in this one: unreferenced object 0xffff88003b6696e0 (size 32): comm "cat", pid 2321, jiffies 4294705179 (age 29.434s) hex dump (first 32 bytes): 40 79 1c 81 ff ff ff ff 60 79 1c 81 ff ff ff ff @y......`y...... 50 79 1c 81 ff ff ff ff b0 62 89 81 ff ff ff ff Py.......b...... backtrace: [<ffffffff81c7e3b1>] kmemleak_alloc+0x21/0x50 [<ffffffff811955cb>] kmem_cache_alloc_trace+0x11b/0x190 [<ffffffff811c87dc>] single_open+0x3c/0xc0 [<ffffffff81896495>] info_proc_open+0x15/0x20 [<ffffffff8120c6d7>] proc_reg_open+0xb7/0x160 [<ffffffff811a1a5c>] do_dentry_open+0x1cc/0x280 [<ffffffff811a296a>] finish_open+0x4a/0x60 [<ffffffff811b14d7>] do_last+0xb07/0xdb0 [<ffffffff811b1842>] path_openat+0xc2/0x4f0 [<ffffffff811b1cac>] do_filp_open+0x3c/0xa0 [<ffffffff811a2dcc>] do_sys_open+0x11c/0x1c0 [<ffffffff811a2e8c>] sys_open+0x1c/0x20 [<ffffffff81ca3d69>] system_call_fastpath+0x16/0x1b [<ffffffffffffffff>] 0xffffffffffffffff Signed-off-by: Tommi Rantala <tt.rantala@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
