Version: 1

i2c: spacemit: fix spurious IRQ handling returning IRQ_HANDLED
91890c4 
When the interrupt status register reads zero (no interrupt pending
from this device), the handler should return IRQ_NONE. Returning
IRQ_HANDLED incorrectly claims the interrupt was serviced, which can
prevent other devices sharing the same IRQ line from receiving their
interrupts.

Fix this by returning IRQ_NONE instead of IRQ_HANDLED when the
status register is zero.
