| Subject | [PATCH v5 2/5] ACPICA: Parser: Fix a regression in LoadTable support |
| Message-ID | <skplv-6JY-1@gated-at.bofh.it> |
ACPICA commit a78506e0ce8ab1d20db2a055d99cf9143e89eb29
LoadTable allows an alternative RootPathString than the default "\", while
the new table execution support fails to keep this logic.
This regression can be detected by ASLTS - TLT0.tst4, this patch fixes this
regression.
Linux upstream is not affected by this regression as we haven't enabled the
new table execution support there. BZ 1326, Lv Zheng.
