From: Mika Westerberg Date: Wed, 6 May 2015 10:29:07 +0000 (+0300) Subject: i2c / ACPI: Use 0 to indicate that device does not have interrupt assigned X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dab472eb931bc2916fa779e56deccd0ec319cf5b;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git i2c / ACPI: Use 0 to indicate that device does not have interrupt assigned This is the convention used in most parts of the kernel including DT counterpart of I2C slave enumeration. To make things consistent do the same for ACPI I2C slave enumeration path as well.
