Peter Senna Tschudin 07d783fd83 staging: goldfish: Fix pointer cast for 32 bits
As the first argument of gf_write64() was of type unsigned long, and as
some calls to gf_write64() were casting the first argument from void *
to u64 the compiler and/or sparse were printing warnings for casts of
wrong sizes when compiling for i386.

This patch changes the type of the first argument of gf_write64() to
const void *, and update calls to the function. This change fixed the
warnings and allowed to remove casts from 3 calls to gf_write64().

In addition gf_write64() was renamed to gf_write_ptr() as the name was
misleading because it only writes 32 bits on 32 bit systems.

gf_write_dma_addr() was added to handle dma_addr_t values which is
used at drivers/staging/goldfish/goldfish_audio.c.

Jiri Kosina 0e4f93e501 goldfish: goldfish_tty_probe() is not using 'i' any more
The only place where 'i' has been used was a dead code that
got removed by 2a2483685a ("goldfish: remove unreachable line
of code"). Remove the last reference to the variable as well.

Dan Carpenter fda2b418a1 goldfish: off by one in goldfish_tty_console_setup()
The goldfish_ttys[] array has "goldfish_tty_line_count" number of
elements.  It's allocated in goldfish_tty_create_driver().  This test
should be >= instead of >.

Paul Gortmaker f8e87cb4a1 tty: delete non-required instances of include <linux/init.h>
None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>.  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

Arve Hjønnevåg 666b7793d4 goldfish: tty driver
This provides a console driver for the Goldfish virtual platform. The original
is from Arve with changes from Jun Nakajima and Tom Keel. This has been then
been ported to the current kernel and to the tty port mechanism by Alan Cox.
In the process it gained proper POSIX semantics and vhangup works. The default
name is not ttyS as this belongs to the 8250 driver. Instead ttyGFx is now used.

In the normal usage case the first port serves as a kernel logging console and
the second one carries various other data streams for the emulation.
