Subject: timekeeping: Switch HAS_PERSISTENT_CLOCK to ALWAYS_USE_PERSISTENT_CLOCK
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6f16eebe1ff82176339a0439c98ebec9768b0ee2;p=openwrt%2Fstaging%2Fblogic.git

timekeeping: Switch HAS_PERSISTENT_CLOCK to ALWAYS_USE_PERSISTENT_CLOCK

Jason pointed out the HAS_PERSISTENT_CLOCK name isn't
quite accurate for the config, as some systems may have
the persistent_clock in some cases, but not always.

So change the config name to the more clear
ALWAYS_USE_PERSISTENT_CLOCK.
