Fix typos and add the following to the scripts/spelling.txt:
comsume||consume
comsumer||consumer
comsuming||consuming
I see some variable names with this pattern, but this commit is only
touching comment blocks to avoid unexpected impact.

Inside ioc4_attach_local() 4 memory was allocated using kzalloc and
assign it to ports[] within loop. When kzalloc fails inside loop,
it returns error without freeing previously allocated memory and we
may have memory leak. Fix this by freeing ports[] before return.

We should not be doing assignments within an if () block
so fix up the code to not do this.

ioc4_serial_attach_one() is used only in this file.
Also, ioc4_serial is not used; it can be removed.
Fix the following sparse warnings:
drivers/tty/serial/ioc4_serial.c:300:3: warning: symbol 'ioc4_serial' was not declared. Should it be static?
drivers/tty/serial/ioc4_serial.c:2771:1: warning: symbol 'ioc4_serial_attach_one' was not declared. Should it be static?

Now, we start converting tty buffer functions to actually use
tty_port. This will allow us to get rid of the need of tty in many
call sites. Only tty_port will needed and hence no more
tty_port_tty_get in those paths.
Now, the one where most of tty_port_tty_get gets removed:
tty_flip_buffer_push.
IOW we also closed all the races in drivers not using tty_port_tty_get
at all yet.
Also we move tty_flip_buffer_push declaration from include/linux/tty.h
to include/linux/tty_flip.h to all others while we are changing it
anyway.

One point is to have less places where we actually need tty pointer.
The other is that low_latency is bound to buffer processing and
buffers are now in tty_port. So it makes sense to move low_latency to
tty_port too.

This will let us sort out a whole pile of tty related races. The
alternative would be to keep points and refcount the termios objects.
However
1. They are tiny anyway
2. Many devices don't use the stored copies
3. We can remove a pty special case

We want to know the value of the atomic variable in intr_connect after
the increment. But atomic_inc doesn't, per definition, return the
value. It is just a pure coincidence that ia64 defines atomic_inc as
atomic_inc_return.
So fix this mistake by using atomic_inc_return properly.

linux/tty_flip.h is included in linux/serial_core.h. But this may (and
will) change in the future. Then we would get build errors such as:
.../tty/serial/max3107.c: In function ‘put_data_to_circ_buf’:
.../tty/serial/max3107.c:149:2: error: implicit declaration of function ‘tty_insert_flip_string’
So fix all the drviers which call tty flip buffer helpers to really
include linux/tty_flip.h. And also make sure that those include
linux/tty.h when operating with struct tty_struct.

The serial drivers are really just tty drivers, so move them to
drivers/tty/ to make things a bit neater overall.
This is part of the tty/serial driver movement proceedure as proposed by
Arnd Bergmann and approved by everyone involved a number of months ago.
