Format specifier %p can leak kernel addresses while not valuing the
kptr_restrict system settings. When kptr_restrict is set to (1), kernel
pointers printed using the %pK format specifier will be replaced with 0's.
Debugging Note : &pK prints only Zeros as address. If you need actual
address information, write 0 to kptr_restrict.
echo 0 > /proc/sys/kernel/kptr_restrict

commit 2ce9d2272b98743b911196c49e7af5841381c206 upstream.
Some code (all error handling) submits CDBs that are allocated
on the stack. This breaks with CB/CBI code that tries to create
URB directly from SCSI command buffer - which happens to be in
vmalloced memory with vmalloced kernel stacks.
Let's make copy of the command in usb_stor_CB_transport.

commit 5fb2c782f451a4fb9c19c076e2c442839faf0f76 upstream.
This device automatically switches itself to another mode (0x1405)
unless the specific access pattern of Windows is followed in its
initial mode. That makes a dirty unmount of the internal storage
devices inevitable if they are mounted. So the card reader of
such a device should be ignored, lest an unclean removal become
inevitable.
This replaces an earlier patch that ignored all LUNs of this device.
That patch was overly broad.
