[PATCH 11/11] ARM: OMAP3: Clean up spurious interrupt check logic

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Roger Quadros <ext-roger.quadros@xxxxxxxxx>

SPURIOUSIRQ is contained in bits 31:7 of INTC_SIR, so
INTC_SIR must be right shifted by 7, not 6.

No change in logic, only changes for better readability.
Refer to register definition of INTCPS_SIR_IRQ in OMAP3 Manual.
