Subject: [PATCH 0/2] tools/perf: tools: Fix perf build issues

Hi,

These are the patches to fix the perf build issues which I reported in
the previous email.

https://lore.kernel.org/lkml/162037766527.94840.4323848545957010011.stgit@devnote2/

There are 2 issues I found and are fixed with these patches.

 - Since the EXTRA_CLFAGS/WARNINGS are listed before -Wall/-Wextra in
   CFLAGS, all -Wno-* flags in the EXTRA_CFLAGS/WARNINGS are ignored.
   This makes EXTRA_WARNINGS ignored and developers can not use EXTRA_CLFAGS
   for debugging compiler warnings.

 - Clang's missing-field-initializers warning is too sensitive compared
   with GCC. I think "{ NULL }" kind of syntax is allowed for simplify code.


Thank you,

---
