Subject: bpf: Remove redundant assignment to pointer t
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=73b6eae583f44e278e19489a411f9c1e22d530fc;p=linux.git

bpf: Remove redundant assignment to pointer t

The pointer t is being initialized with a value that is never read. The
pointer is re-assigned a value a littler later on, hence the initialization
is redundant and can be removed.
