From: Petr Štetiar Date: Mon, 28 Mar 2022 09:35:57 +0000 (+0200) Subject: generic: backport 5.16 fix for hv utils build failure X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=972f2bff6add81e17728e3dd2c1f972ffa39600d;p=openwrt%2Fstaging%2Fxback.git generic: backport 5.16 fix for hv utils build failure Backports following fix: hv: utils: add PTP_1588_CLOCK to Kconfig to fix build The hyperv utilities use PTP clock interfaces and should depend a a kconfig symbol such that they will be built as a loadable module or builtin so that linker errors do not happen.
