Subject: serial: kgdb_nmi: remove redundant initialization of variable c
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1e49b0954c91019f51ce22cd0bce2297dd928f8c;p=linux.git

serial: kgdb_nmi: remove redundant initialization of variable c

The variable c is being initialized with a value that is never
read, it is being updated later on. The assignment is redundant and
can be removed.
