[PATCH] serial: kgdb_nmi: remove redundant initialization of variable c

From: Colin King
Date: Thu May 13 2021 - 19:02:28 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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.

Addresses-Coverity: ("Unused value")
