X-Git-Tag: v5.15.139~57 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=516235e7b35f660cdd360c110819284921a5bac0;p=thirdparty%2Fkernel%2Fstable.git powerpc/imc-pmu: Use the correct spinlock initializer. [ Upstream commit 007240d59c11f87ac4f6cfc6a1d116630b6b634c ] The macro __SPIN_LOCK_INITIALIZER() is implementation specific. Users that desire to initialize a spinlock in a struct must use __SPIN_LOCK_UNLOCKED(). Use __SPIN_LOCK_UNLOCKED() for the spinlock_t in imc_global_refc.
