+Subject: [PATCH 30/62] drm/i915: Drop the irqs_disabled() check
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.1/older/patches-6.1.69-rt21.tar.xz
+
+The !irqs_disabled() check triggers on PREEMPT_RT even with
+i915_sched_engine::lock acquired. The reason is the lock is transformed
+into a sleeping lock on PREEMPT_RT and does not disable interrupts.
+
+There is no need to check for disabled interrupts. The lockdep
+annotation below already check if the lock has been acquired by the
+caller and will yell if the interrupts are not disabled.
+
+Remove the !irqs_disabled() check.
