Subject: Use const for the usbi_parse_descriptor() format string
X-Git-Tag: upstream/1.0.21~879
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;ds=sidebyside;h=3b41c31d3fa2c1f93649cc5fc0f59acbf3efd5a1;p=platform%2Fupstream%2Flibusb.git

Use const for the usbi_parse_descriptor() format string

Constant strings should be "const char *" instead of "char *". Silence
"discards qualifiers from pointer target type" warnings. Fixes #61.
