From d9b4330adec006c2e8907bdcacd9dcc0e8874d18 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Fri, 8 Feb 2013 15:14:16 +0200 Subject: usb: dwc3: core: don't forget to free coherent memory commit 3921426 (usb: dwc3: core: move event buffer allocation out of dwc3_core_init()) introduced a memory leak of the coherent memory we use as event buffers on dwc3 driver. If the driver is compiled as a dynamically loadable module and use constantly loads and unloads the driver, we will continue to leak the coherent memory allocated during ->probe() because dwc3_free_event_buffers() is never called during ->remove().
