Date: Mon, 28 Aug 2023 19:00:27 +0530	[thread overview]
Message-ID: <20230828133033.11988-8-quic_kriskura@quicinc.com> (raw)
In-Reply-To: <20230828133033.11988-1-quic_kriskura@quicinc.com>

Cleanup setup irq call by implementing a new prep_irq helper function
and using it to request threaded IRQ's.
