From 5e3e4eb1bf212d9ae4997ebcbe2fdfb348b70213 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Tue, 2 Aug 2011 22:22:46 -0700 Subject: [PATCH] Input: polldev - immediately poll device upon opening To allow open/ioctl(EVIOCGABS)/close use pattern for polled devices read the device in context of open() call instead of offloading the first read to a workqueue. This will ensure that once call to open() returns device would have cached reasonably recent axis values that can be retrieved via appropriate ioctl.
