[PATCH v2 0/4] perf timechart: Fix memory leaks

[Namhyung Kim <namhyung@kernel.org>]

Hello,

This patchset fixes memory leaks in the perf timechart code.
I've extended and verified the timechart test with ASAN.

v2)
 * use zfree() and explicit clear for potential misuse  (Arnaldo)
 * fix a wrong condition in the draw_wakeups()  (Sashiko)
 * move misplaced hunk in the second commit to the first
 
While it doesn't depend on my other timechart patch series [1], fixing
the memory leaks entirely requires some work there.  So I'd suggest
applying this after the previous work.

Thanks,
Namhyung
