soc: ti: smartreflex: Use IRQF_NO_AUTOEN flag in request_irq()
[ Upstream commit 16a0a69244240cfa32c525c021c40f85e090557a ]
If request_irq() fails in sr_late_init(), there is no need to enable
the irq, and if it succeeds, 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: 1279ba5916f6 ("OMAP3+: SR: disable interrupt by default")
