Subject: [PATCH net-next v2 3/6] net: ipa: enable IPA interrupt handlers separate from registration
Expose ipa_interrupt_enable() and have functions that register
IPA interrupt handlers enable them directly, rather than having the
registration process do that. Do the same for disabling IPA
interrupt handlers.
Signed-off-by: Alex Elder <elder@...aro.org>

v2 Declared enum ipa_irq_id at the top of "ipa_interrupt.c".
