From c737bcf92ea206d3b5d351890f1ade9e12ad4cbe Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires <benjamin.tissoires@gmail.com> Date: Tue, 4 Dec 2012 16:27:50 +0100 Subject: [PATCH] HID: i2c-hid: i2c_hid_get_report may fail If i2c_hid_get_report fails, exit i2c_hid_init_report. The printk log is already called by i2c_hid_get_report, so no need to add some more printks.
