Subject: [PATCH] KVM: fix sparse warnings: context imbalance
Impact: Attribute function with __acquires(...) resp. __releases(...).
Fix this sparse warnings:
arch/x86/kvm/i8259.c:34:13: warning: context imbalance in 'pic_lock' - wrong count at exit
arch/x86/kvm/i8259.c:39:13: warning: context imbalance in 'pic_unlock' - unexpected unlock
