From: Johan Hovold Date: Fri, 26 Sep 2014 10:55:30 +0000 (+0200) Subject: mfd: core: Add helper function to register hotplug devices X-Git-Tag: firefly_0821_release~176^2~2781^2~37^2~7 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=a7975473cc41773d9f6d8ea72b48c7656e6cd0f6;p=firefly-linux-kernel-4.4.55.git mfd: core: Add helper function to register hotplug devices Hot-pluggable multi-function devices should always be registered with PLATFORM_DEVID_AUTO to avoid name collisions on the platform bus. This helper also hides the memory map and irq parameters, which aren't used by hot-pluggable (e.g. USB-based) devices.
