From 04ce40a61a9164f82065eade491099b185c17a65 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Wed, 6 Sep 2017 16:42:26 -0700 Subject: [PATCH] Input: uinput - remove uinput_allocate_device() There is no need for this wrapper; let's use input_allocate_device() directly, and complete initialization in uinput_create_device().
