[PATCH v2 5/5] drm/panthor: Don't update MMU_INT_MASK in panthor_mmu_irq_handler()

[Boris Brezillon]

Interrupts are automatically unmasked in
panthor_mmu_irq_threaded_handler() when the handler returns. Unmasking
prematurely might generate spurious interrupts if the IRQ line is
shared.

Changes in v2:
- New patch
