Subject: [POWERPC] Add missing native dcr dcr_ind_lock spinlock
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=853265e588153dca22c82b84df39bbb40abd7ad0;p=openwrt%2Fstaging%2Fblogic.git

[POWERPC] Add missing native dcr dcr_ind_lock spinlock

The include/asm-powerpc/dcr-native.h declares extern spinlock_t dcr_ind_lock;
but it's actually isn't defined. This patch adds a missing dcr_ind_lock.
