Re: [PATCH] PCI: tegra: Convert struct tegra_msi mask_lock into raw spinlock

The tegra_msi_irq_unmask() function may be called from a PCI driver request_threaded_irq() function. This triggers kernel/irq/manage.c __setup_irq() which locks raw spinlock &desc->lock descriptor lock and with that descriptor lock held, calls tegra_msi_irq_unmask().

Since the &desc->lock descriptor lock is a raw spinlock , and the tegra_msi .mask_lock is not a raw spinlock, this setup triggers 'BUG: Invalid wait context' with CONFIG_PROVE_RAW_LOCK_NESTING=y .
