RE: [Devel] [PATCH 3/3] ACPICA: Remove use of __DATE__ macro

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I've added this patch into the 201501 ACPICA materials for review:
https://github.com/acpica/acpica/pull/61
If it is merged, it will appear in Linux kernel after 201501 ACPICA release.
Thanks for reporting.

Best regards
-Lv
