Subject: [PATCH][next] tty: jsm: Remove redundant assignment to variable linestatus
Date: Fri, 16 Feb 2024 12:17:32 +0000 [thread overview]
Message-ID: <20240216121732.2106445-1-colin.i.king@gmail.com> (raw)
The variable linestate being assigned a value that is never read, the
following continue statement jumps to the end of the while-loop and then
it is re-assigned a new value. The assignment is redundant and can be
removed.
Cleans up clang scan build warning:
drivers/tty/serial/jsm/jsm_cls.c:398:4: warning: Value stored
to 'linestatus' is never read [deadcode.DeadStores]
