[PATCH] serial: meson: remove redundant initialization of variable id

From: Colin King <hidden>
Date: 2021-04-26 10:11:16
Also in: kernel-janitors, linux-amlogic, linux-serial, lkml
Subsystem: the rest, tty layer and serial drivers · Maintainers: Linus Torvalds, Greg Kroah-Hartman, Jiri Slaby

From: Colin Ian King <redacted>

The variable id being initialized with a value that is never read
and it is being updated later with a new value. The initialization is
redundant and can be removed. Since id is just being used in a for-loop
inside a local scope, move the declaration of id to that scope.

Addresses-Coverity: ("Unused value")
