patch "dyndbg: fix parsing file query without a line-range suffix" added to char-misc-linus

This is a note to let you know that I've just added the patch titled

dyndbg: fix parsing file query without a line-range suffix

to my char-misc git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

Subject: dyndbg: fix parsing file query without a line-range suffix

Query like 'file tcp_input.c line 1234 +p' was broken by
commit aaebe329bff0 ("dyndbg: accept 'file foo.c:func1' and 'file foo.c:10-100'") because a file name without a ':' now makes the loop in ddebug_parse_query() exits early before parsing the 'line 1234' part. As a result, all pr_debug() in tcp_input.c will be enabled, instead of only the one on line 1234. Changing 'break' to 'continue' fixes this.
