Subject: WATCHDOG: txx9wdt: Add missing clock (un)prepare calls for CCF
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=39a3b6355329397c30441b62c940bb9cecec0448;p=openwrt%2Fstaging%2Fblogic.git

WATCHDOG: txx9wdt: Add missing clock (un)prepare calls for CCF

While the custom minimal TXx9 clock implementation doesn't need or use
clock (un)prepare calls (they are dummies if !CONFIG_HAVE_CLK_PREPARE),
they are mandatory when using the Common Clock Framework.

Hence add them, to prepare for the advent of CCF.
