5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jinjie Ruan <ruanjinjie@xxxxxxxxxx>
[ Upstream commit 799a9225997799f7b1b579bc50a93b78b4fb2a01 ]
disable_irq() after request_irq() still has a time gap in which
interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will
disable IRQ auto-enable when request IRQ.
Fixes: bbb96dc7fa1a ("enetc: Factor out the traffic start/stop procedures")
