commit b321a38d2407c7e425c54bc09be909a34e49f740 upstream.
The oversampling ratio is controlled using the oversampling pins,
OS [2:0] with OS2 being the MSB control bit, and OS0 the LSB control
bit.The gpio connected to the OS2 pin is not being set correctly, only OS0
and OS1 pins are being set. Fix the typo to allow proper control of the
oversampling pins.Signed-off-by: Eva Rachel Retuya

commit 3c3dd1e058cb01e835dcade4b54a6f13ffaeaf7c upstream.
Function klsi_105_open() calls usb_control_msg() (to "enable read") and
checks its return value. When the return value is unexpected, it only
assigns the error code to the return variable retval, but does not
terminate the exception path. This patch fixes the bug by inserting
"goto err_generic_close;" when the call to usb_control_msg() fails.Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")

commit 7b01738112608ce47083178ae2b9ebadf02d32cc upstream.
This fixes a regression which was introduced by commit f1bddbb, by
reverting a small fragment of commit 855ed04.If the following conditions were met, usb_gadget_probe_driver() returned
0, although the call was unsuccessful:
1. A particular UDC was specified by thge gadget driver (using member
"udc_name" of struct usb_gadget_driver).
2. The UDC with this name is available.
3. Another gadget driver is already bound to this gadget.
4. The gadget driver has the "match_existing_only" flag set.
In this case, the return code variable "ret" is set to 0, the return
code of a strcmp() call (to check for the second condition).This also fixes an oops which could occur in the following scenario:
1. Two usb gadget instances were configured using configfs.
2. The first gadget configuration was bound to a UDC (using the configfs
attribute "UDC").
3. It was tried to bind the second gadget configuration to the same UDC
in the same way. This operation was then wrongly reported as being
successful.
4. The second gadget configuration's "UDC" attribute is cleared, to
unbind the (not really bound) second gadget configuration from the UDC.] __list_del_entry+0x29/0xc0

/* can abort random command */To do abort operation correctly, we have to wait both of COMP_CMD_STOP
event and negation of CMD_RING_RUNNING.But like above, while timeout handler is waiting negation of
CMD_RING_RUNNING, event handler can restart cmd_ring. So timeout
handler never be notice negation of CMD_RING_RUNNING, and retry of
CMD_RING_ABORT can abort random command (BTW, I guess retry of
CMD_RING_ABORT was workaround of this race).To fix this race, this moves xhci_handle_stopped_cmd_ring() to
xhci_abort_cmd_ring(). And timeout handler waits COMP_CMD_STOP event.At this point, timeout handler is owner of cmd_ring, and safely
restart cmd_ring by using xhci_handle_stopped_cmd_ring().[FWIW, as bonus, this way would be easily extend to add CMD_RING_PAUSE

commit 0dd408425eb21ddf26a692b3c8044c9e7d1a7948 upstream.
Fix NULL-pointer dereference when initialising URBs at open should a
non-EPIC device lack a bulk-in or interrupt-in endpoint.Unable to handle kernel NULL pointer dereference at virtual address 00000028
...
PC is at edge_open+0x24c/0x3e8 [io_edgeport]Note that the EPIC-device probe path has the required sanity checks so
this makes those checks partially redundant.Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")

Cancel the heartbeat work on driver unbind in order to avoid I/O after
disconnect in case the port is held open.Note that the cancel in release() is still needed to stop the heartbeat
after late probe errors.Fixes: 26c78daade0f ("USB: io_ti: Add heartbeat to keep idle EP/416 ports from disconnecting")

commit 4f9785cc99feeb3673993b471f646b4dbaec2cc1 upstream.
In case a device is left in "boot-mode" we must not register any port
devices in order to avoid a NULL-pointer dereference on open due to
missing endpoints. This could be used by a malicious device to trigger
an OOPS:Unable to handle kernel NULL pointer dereference at virtual address 00000030
