[PATCH 09/14] HID: i2c-hid: i2c_hid_get_report may fail

From: Benjamin Tissoires <hidden>
Date: 2012-12-04 15:34:56
Also in: linux-input, lkml
Subsystem: hid core layer, the rest · Maintainers: Jiri Kosina, Benjamin Tissoires, Linus Torvalds

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.
