Subject: powerpc/imc-pmu: Use the correct spinlock initializer.
Git-commit: 007240d59c11f87ac4f6cfc6a1d116630b6b634c
Patch-mainline: v6.7-rc1
References: git-fixes
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.
Fixes: 76d588dddc459 ("powerpc/imc-pmu: Fix use of mutex in IRQs disabled section")
