Subject: tree: use strtou32 to read lba_size
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=adb28c44cbc201faa1d9a908383de83df94a3413;p=users%2Fsagi%2Flibnvme.git

tree: use strtou32 to read lba_size

The lba_size variable is of type int, thus we should use nvme_strtou32
and avoid overwriting memory.
