Subject: selftests: ptp: Fix incorrect kernel headers search path
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=01ede99e9de16e7a1ed689c99f41022aa878f2f4;p=linux.git

selftests: ptp: Fix incorrect kernel headers search path

Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents
building against kernel headers from the build environment in scenarios
where kernel headers are installed into a specific output directory
(O=...).
