The blkdev_report_zones produces a harmless warning when -Wmaybe-uninitialized is set, after gcc gets a little confused about the multiple 'goto' here: block/blk-zoned.c: In function 'blkdev_report_zones': block/blk-zoned.c:188:13: error: 'nz' may be used uninitialized in this function [-Werror=maybe-uninitialized] Moving the assignment to nr_zones makes this a little simpler while also avoiding the warning reliably. I'm removing the extraneous initialization of 'int ret' in the same patch, as that is semi-related and could cause an uninitialized use of that variable to not produce a warning.
