From: Benjamin Tissoires Date: Tue, 4 Dec 2012 15:27:50 +0000 (+0100) Subject: HID: i2c-hid: i2c_hid_get_report may fail X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c737bcf92ea206d3b5d351890f1ade9e12ad4cbe;p=linux-beck.git 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.
