From: Octavian Purdila Date: Wed, 23 Sep 2015 09:02:01 +0000 (+0300) Subject: iio: remove gpio interrupt probing from drivers that use a single interrupt X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0f0796509c07;p=linux-beck.git 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.
