Subject: ubifs: Remove unreachable code in dbg_check_ltab_lnum
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=788cd161f99638db81b4c9ce836dbdf9a65c7701;p=linux.git

ubifs: Remove unreachable code in dbg_check_ltab_lnum

Because there is no break statement in the dead loop above,it is
impossible to execute the 'err=0' statement.Delete the code that
will never execute.

Fixes: 6fb324a4b0c3 ("UBIFS: allocate ltab checking buffer on demand")
