Subject: CRISv32: Avoid warning of unused variable
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=00c5794d2df7a8586d4c1dc11c54ea5714fbe17f;p=openwrt%2Fstaging%2Fblogic.git

CRISv32: Avoid warning of unused variable

Avoids the warning about:
warning: 'bite_in_progress' defined but not used [-Wunused-variable]

Variable is only used if the Kconfig CONFIG_ETRAX_WATCHDOG_NICE_DOGGY
is set.
