Subject: [PATCH] floppy: Remove redundant assignment to nr_sectors
Date: Fri, 30 Apr 2021 17:26:45 +0800	[thread overview]
Message-ID: <> (raw)

Variable nr_sectors is set to zero but this value is never
read as it is overwritten later on, hence it is a redundant
assignment and can be removed.

Clean up the following clang-analyzer warning:

drivers/block/floppy.c:2333:2: warning: Value stored to 'nr_sectors' is
never read [clang-analyzer-deadcode.DeadStores].
