fsl_udc_release() calls dma_free_coherent() with an inappropriate device passed to it, and since the device has no dma_ops, the following oops pops up: Kernel BUG at d103ce9c [verbose debug info unavailable] Oops: Exception in kernel mode, sig: 5 [#1] ... NIP [d103ce9c] fsl_udc_release+0x50/0x80 [fsl_usb2_udc] LR [d103ce74] fsl_udc_release+0x28/0x80 [fsl_usb2_udc] Call Trace: [cfbc7dc0] [d103ce74] fsl_udc_release+0x28/0x80 [fsl_usb2_udc] [cfbc7dd0] [c01a35c4] device_release+0x2c/0x90 [cfbc7de0] [c016b480] kobject_cleanup+0x58/0x98 [cfbc7e00] [c016c52c] kref_put+0x54/0x6c [cfbc7e10] [c016b360] kobject_put+0x34/0x64 [cfbc7e20] [c01a1d0c] put_device+0x1c/0x2c [cfbc7e30] [d103dbfc] fsl_udc_remove+0xc0/0x1e4 [fsl_usb2_udc] ... This patch fixes the issue by passing dev->parent, which points to a correct device.
