This patch fixes this error: invalid type argument of ‘->’ (have ‘struct ktermios’).

There were changes in the tty layer's API. Access to the termios flags changed from tty->termios->*flag* to tty->termios.*flag*.

[1] introduced down_write in zram_slot_free_notify to prevent race
between zram_slot_free_notify and zram_bvec_[read|write]. The race
could happen if somebody who has right permission to open swap device
is reading swap device while it is used by swap in parallel.

However, zram_slot_free_notify is called with holding spin_lock of
swap layer so we shouldn't avoid holing mutex. Otherwise, lockdep
warns it.

This patch adds new list to handle free slot and workqueue
so zram_slot_free_notify just registers slot index to be freed and
registers the request to workqueue. If workqueue is expired,
it holds mutex_lock so there is no problem any more.

If any I/O is issued, zram handles pending slot-free request
caused by zram_slot_free_notify right before handling issued
request because workqueue wouldn't be expired yet so zram I/O
request handling function can miss it.

Lastly, when zram is reset, flush_work could handle all of pending
free request so we shouldn't have memory leak.

NOTE: If zram_slot_free_notify's kmalloc with GFP_ATOMIC would be
failed, the slot will be freed when next write I/O write the slot.

    in swap free notify path]

[1] tried to fix invalid memory access on zram->disk but it didn't
fix properly because get_disk failed during module exit path.

Actually, we don't need to reset zram->disk's capacity to zero
in module exit path so that this patch introduces new argument
"reset_capacity" on zram_reset_divice and it only reset it when
reset_store is called.

DIO subdevices always handle the INSN_CONFIG_DIO_{INPUT,OUTPUT} instructions
to configure the DIO channels. They also always handle the INSN_CONFIG_DIO_QUERY
instruction to query the configuration of a DIO channel.

Introduce a helper function to handle the (*insn_config) boilerplate for
comedi DIO subdevices. This function has the same paramters as (*insn_config)
functions with an additional parameter to allow the caller to pass a 'mask'
value for grouped DIO channels.

This function returns:

  0 if the instruction was successful but requires additional handling by
  the caller (INSN_CONFIG_DIO_{INPUT,OUTPUT}

  insn->n if the instruction was handled (INSN_CONFIG_DIO_QUERY)

  -EINVAL for all unhandled instructions

The caller is responsible for actually configuring the hardware based on
the configuration (s->io_bits).

This patch fix following issues reported by Dan:-

1) There is no check limiting the size to 32 and it could be up to
   253 bytes.
2) Use defines instead of magic numbers.
3) The oz_farewell struct is supposed to be a variable length struct
   but the variable part is put in the middle.  It doesn't make any
   sense to put the length of the variable size array after then end
   of the array because we can never find it again!  Put the
   variable size array at the end.  Make it a zero length array.
   u8 len;
   u8 report[0];
4) In oz_add_farewell() we do this:

	f = kmalloc(sizeof(struct oz_farewell) + len - 1, GFP_ATOMIC);

    The "- 1" refers to sizeof(f->report) but because it was a magic
    number then it was missed when the sizeof(f->report) changed.
5) In [patch 6/6] we set the ->len member.  But because it is at the
   end of a variable length array with no limit check the remote
   attacker can just rewrite it using the memcpy() on the next line.
