[Dle-develop] [PATCH -tip v3 3/9] perf probe: Fix bugs in line range finder

[Masami H. <mhi...@re...>]

Fix find_line_range_by_line() to init line_list and remove
misconseptional found marking which should be done when
real lines are found (if there is no lines probe-able,
find_line_range() should return 0).
