Darwish The usage of in_interrupt() in drivers is phased out for various reasons. Documenting calling contexts of functions with 'in_interrupt()' or '!in_interrupt()' is imprecise: For a function which might sleep the condition is preemptible task context, which is not what '!in_interrupt()' describes. Replace the context docummentation with plain text and make them match reality. Signed-off-by: Ahmed S.
