| Subject: kbuild: drop -Wno-unknown-warning-option from clang options |
| |
| From: Masahiro Yamada <yamada.masahiro@socionext.com> |
| |
| commit a0ae981eba8f07dbc74bce38fd3a462b69a5bc8e upstream. |
| |
| Since commit c3f0d0bc5b01 ("kbuild, LLVMLinux: Add -Werror to |
| cc-option to support clang"), cc-option and friends work nicely |
| for clang. |
| |
| However, -Wno-unknown-warning-option makes clang happy with any |
| unknown warning options even if -Werror is specified. |
| |
| Once -Wno-unknown-warning-option is added, any succeeding call of |
| cc-disable-warning is evaluated positive, then unknown warning |
| options are accepted. This should be dropped. |
