From e6f2813a6d3fd924a399f8b19bcd8b11487155bc Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Wed, 13 Jul 2016 18:06:01 +0200 Subject: HID: wacom: EKR: add a worker to add/remove resources on addition/removal wacom_remote_status_irq() sends information of addition/removal of EKR. We want to allocate one input node per remote, so better having this in a separate worker, not handled in the IRQ directly.
