From dca6951f5adc5262ae2689cf2656628b309eabd7 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 19 Oct 2017 12:58:21 +0200 Subject: f2fs: remove several redundant assignments There are several assignments to variables that are redundant as the values are never read when the variables are updated later and so the redundant statements can be safely removed.
