[PATCH] relay: remove redundant assignment to pointer buf

From: Colin Ian King
Date: Sun May 08 2022 - 17:22:03 EST


Pointer buf is being assigned a value that is not being read, buf
is being re-assigned in the next starement. The assignment is
redundant and can be removed.

Cleans up clang scan build warning:
kernel/relay.c:443:8: warning: Although the value stored to 'buf' is
used in the enclosing expression, the value is never actually read
from 'buf' [deadcode.DeadStores]
