Subject: media: gspca: dtcs033: use %*ph to print small buffer
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c32678eac48ad3c0ecad47f8879f9017390e358a;p=openwrt%2Fstaging%2Fblogic.git

media: gspca: dtcs033: use %*ph to print small buffer

Use %*ph format to print small buffer as hex string.

Remove newline at the end of the format string as it would be duplicated
by the one supplied as last argument.
