This patch replaces the direct invocation of the irq_mask() and
git grep 'This patch' Documentation/process/
irq_disable() hooks with simplified code that leverages the irq_disable() kernel infrastructure. This higher-level function checks the interrupt's state to prevent redundant operations. Additionally, the IRQ_DISABLE_UNLAZY status flag is set to ensure that, for interrupt chips lacking an irq_disable callback, the disable operation is handled using the lazy approach.
Not that it matters much anymore, but the last sentence does not make
sense:
Set the UNLAZY flag so disable is handled using the LAZY approach ...
Thanks,
