Subject: btrfs-progs: Fix getopt on arm/ppc platforms
X-Git-Tag: upstream/4.16.1~3225
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=309e50c7634f0603dab866ad699e7981e9fca004;p=platform%2Fupstream%2Fbtrfs-progs.git

btrfs-progs: Fix getopt on arm/ppc platforms

(same as commit bb0eabc383e9a3fde7cdb02591ca88243f3e31fb)
There, 'char' is unsigned, so once assigned '-1' from getopt, it gets
the value 255. Then, it compared to '-1' gives false.
