[PATCH] btrfs: scrub: Remove redundant initialization of increment
From: Jiapeng Chong
Date: Fri Jan 21 2022 - 06:42:55 EST
increment is being initialized to map->stripe_len but this is never
read as increment is overwritten later on. Remove the redundant
initialization.
Cleans up the following clang-analyzer warning:
fs/btrfs/scrub.c:3193:6: warning: Value stored to 'increment' during its
initialization is never read [clang-analyzer-deadcode.DeadStores].
