relay: remove redundant assignment to pointer buf
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] Link: https://lkml.kernel.org/r/20220508212152.58753-1-colin.i.king@gmail.com Signed-off-by: Colin Ian King <colin.i.king@gmail.com> Reviewed-by: Jens Axboe <axboe@kernel.dk> Cc: Christoph Hellwig <hch@lst.de> Cc: Kalle Valo <kvalo@codeaurora.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
