X-Git-Tag: upstream/snapshot3+hdmi~6860^2~3^2~18
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c6e1733e6fc384ff1a219d7dfcb8b072030ae792;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

ACPICA: iASL: Improved pathname support

For include files, merge the prefix pathname with the file
pathname.  Convert backslashes in all pathnames to forward
slashes, for readability.  Include file pathname changes affect
both #include and Include() type operators.
