[PATCH v2 1/5] block/badblocks: Remove redundant assignments

From: Michal Orzel
Date: Tue Apr 12 2022 - 13:17:25 EST


Get rid of redundant assignments to a variable sectors from functions
badblocks_check and badblocks_clear. This variable, that is a function
parameter, is being assigned a value that is never read until the end of
function.
