Date: Tue, 7 Nov 2017 18:49:14 +0000 From: Colin King <colin.king@...onical.com> To: Evgeniy Polyakov <zbr@...emap.net> Cc: kernel-janitors@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] w1: remove redundant assignments to search_bit and last_rn From: Colin Ian King <colin.king@...onical.com> Variables search_bit and last_rn are assigned values before a while-loop however these initial values are never read (as they are overwritten inside the loop). Thus these initial assignments are redundant and can be removed.
