Some ASUS laptops access EC space from device _INI methods, but do not
provide ECDT for early EC setup. In order to make them function properly,
there is a need to find EC is DSDT before any _INI is called.
Similar functionality was turned on by acpi_fake_ecdt=1 command line
before. Now it is on all the time.

If ib_mad_recv_done_handler() fails to allocate response, then it just
printed a warning and continued, which leads to an oops if the MAD is
being handled for a switch device, because the switch code uses
response without checking for NULL. Fix this by bailing out of the
function if the allocation fails.

Now that ib_find_pkey() ignores the membership bit of P_Keys, there's no
need for ib_sa to look for both 0x7fff and 0xffff in a port's P_Key table.
Signed-off-by: Roland Dreier <rolandd@cisco.com>
ib_find_pkey() is used as a replacement for ib_find_cached_pkey(), and
the original function ignored the membership bit when searching for a
P_Key, so ib_find_pkey() should ignore the bit too.
In particular, IPoIB turns on the P_Key membership bit of limited
membership P_Keys when creating a child interface and looks for the
full membership P_key. This broke if a port was a partial member of a
partition when IPoIB switched from ib_find_cached_pkey() to
ib_find_pkey(), and this change fixes things again.

If, in usb_hid_configure(), we fail to allocate storage for 'usbhid',
"if (!(usbhid = kzalloc(sizeof(struct usbhid_device), GFP_KERNEL)))",
then we'll jump to the 'fail:' label where we have this code:
usb_free_urb(usbhid->urbin);
usb_free_urb(usbhid->urbout);
usb_free_urb(usbhid->urbctrl);
Since we got here because we couldn't allocate storage for 'usbhid',
what we have here is a NULL pointer dereference - ouch...
This patch solves that little problem by adding a new
'fail_no_usbhid:' label after the problematic calls to
usb_free_urb() and jumps to that one instead, in the problem case.
