Subject: ocfs2: remove redundant assignment to variable bit_off
Date: Thu, 22 Jun 2023 11:27:36 +0100
Variable bit_off is being assigned a value that is never read, it is being
re-assigned a new value in the following while loop. Remove the
assignment. Cleans up clang scan build warning:
fs/ocfs2/localalloc.c:976:18: warning: Although the value stored to
'bit_off' is used in the enclosing expression, the value is never
actually read from 'bit_off' [deadcode.DeadStores]
