[PATCH 13/14] HID: i2c-hid: also call i2c_hid_free_buffers in i2c_hid_remove

From: Benjamin Tissoires
Date: Tue Dec 04 2012 - 10:28:45 EST


In the case where the hid driver in charge of handling the hid part
of the device (hid-generic for instance) fails at probe, neither
i2c_hid_start nor i2c_hid_stop are called.
Thus, the buffers allocated in i2c_hid_probe are never freed.
