Subject: [PATCH 1/1] iio: remove gpio interrupt probing from drivers that use a single interrupt
Commit 845c877009cf014b ("i2c / ACPI: Assign IRQ for devices that have
GpioInt automatically") automatically assigns the first ACPI GPIO
interrupt in client->irq, so we can remove the probing code from
drivers that use only one interrupt.
Commit 0f0796509c07c1c7 ("iio: remove gpio interrupt probing from drivers
that use a single interrupt") removes gpio interrupt probing from most
drivers. This patch cleans the remaining ones.
