Subject: [PATCH 2/2] 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
