From f2bd5a9ec5edc307e5f84dc9df14253898e19678 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Thu, 9 Mar 2017 09:47:24 -0800 Subject: [PATCH] Input: axp20x_pek - add axp20x_pek_probe_input_device helper Move all input device related initialization into a new axp20x_pek_probe_input_device helper function. This introduces one functional change, the input device is now registered before the sysfs attr get registered. This is not a problem as the sysfs attr are to configure some long press settings (forced poweroff) in the hardware and do not interact with the input_device. This is a preparation patch for not always registering the input dev.
