Agreed. It works. Thanks, Srinivas -----Original Message----- From: Axel Lin [mailto:axel.lin@xxxxxxxxx] Sent: Wednesday, September 12, 2012 6:40 PM To: Jiri Kosina Cc: Pandruvada, Srinivas; Jonathan Cameron; linux-input@xxxxxxxxxxxxxxx; linux-kernel@xxxxxxxxxxxxxxx Subject: [PATCH 2/2] HID: hid-sensor-hub: Fix sensor_hub_probe error handling Fix below issues in sensor_hub_probe error handling: 1. In the case of goto err_close, hid_hw_stop(hdev) is called twice. Fix it. 2. If fails to allocate MFD device name, we also need to free all successfully allocated names in previous iterations.
