Subject: [spmi-pmic-arb fixes and optimization patches V1 1/9] spmi: pmic-arb: add a print in cleanup_irq

From: Abhijeet Dharmapurikar <adharmap@...eaurora.org>

The cleanup_irq() was meant to clear and mask interrupts that were
left enabled in the hardware but there was no interrupt handler
registered for it. Add an error print when it gets invoked.
