Bug ID: 87991
Summary: hid-sony uses non-DMA-capable transfer buffer, fails
Product: Drivers
Version: 2.5
Kernel Version: 3.17.1
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Input Devices
Assignee: drivers_input-devices@kernel-bugs.osdl.org
Reporter: hector@marcansoft.com
Regression: No
The kernel itself complains:
input: Sony PLAYSTATION(R)3 Controller as
/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.2/1-1.2.2/1-1.2.2.4/1-1.2.2.4:1.0/0003:054C:0268.000A/input/input51

Sixaxis MAC address
sony: probe of 0003:054C:0268.000A failed with error -11
Looks like the code just uses a stack-allocated buffer (from
drivers/hid/hid-sony.c):
__u8 buf[18];
<snip comment>
ret = hid_hw_raw_request(sc->hdev, 0xf2, buf, sizeof(buf),
HID_FEATURE_REPORT, HID_REQ_GET_REPORT);
