mfd: tps65090: Don't tell child devices we have an IRQ if we don't (7d811771) · Commits · 戴 / test

If we weren't given an interrupt we shouldn't tell child devices (like the tps65090 charger) that they have an interrupt. This is needed so that we can support polling mode in the tps65090 charger driver. See also (charger: tps65090: Allow charger module to be used when no irq). Signed-off-by:
