Subject: dynamic_debug: chop off comments in ddebug_tokenize
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8bd6026e88cb2eb1e60ee40c7a1a0786b2db6623;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

dynamic_debug: chop off comments in ddebug_tokenize

If a token begins with #, the remainder of query string is a comment,
so drop it.  Doing it here avoids '#' in quoted strings.
