Since we're just parsing the tuple being passed to this function, we don't
need any device-specific information.
Also, remove the call to pcmcia_validate_cis() from pcmciamtd.c, since it
is already called by the PCMCIA core.

16-bit PCMCIA device handling function definitions are moved to ds.h,
internal definitions to cs_internal.h.

By now, ioaddr_t should only be used by the deprecated ioctl, as it does not
correctly reflect the maximum ioport range at least on some architectures.

The header file for use by (in-kernel) PCMCIA sockets deserved a major
cleanup. Some stuff only used by the pcmcia core modules was moved to
cs_internal.h
Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
cs_internal.h is meant for definitions internal to the PCMCIA core modules.
It must not be included by PCMCIA socket drivers or by PCMCIA device drivers.

Use dev_printk() in cs_error()-based error reporting. While this
function-turned-macro will hopefully go away soon, using dev_printk
simplifies the code much.

CS_BAD_TUPLE was used to denote a bad tuple being passed to the parse
function. Therefore, replace it with -EINVAL and a verbose message.

CS_BAD_ARGS mean a badly written driver or invalid userspace ioctl access,
so translate that to -EINVAL.

These four error values mostly mean a badly written driver, so ds_dbg()
output and -EINVAL seems to be enough.

CS_BAD_TYPE was only used in cs.c and already properly annotated by error
messages. CS_BAD_ATTRIBUTE and CS_BAD_PAGE mean a badly written driver, so
ds_dbg() output and -EINVAL seems to be enough.

CS_NO_MORE_ITEMS is returned by the CIS tuple reading and parsing code if
the end of a tuple chain is reached. As at least one PCMCIA driver relies
on matching this return value, replace it with -ENOSPC which is now
uniquely used for this purpose within the in-kernel pcmcia subsystem.

If a resource is already in use, mark it with -EBUSY. Same for cards already
asleep.

CS_BAD_HANDLE means that something went badly wrong: no parameter was passed,
or the paramater passed wasn't the correct one. Therefore, replace it with
-EINVAL.

CS_OUT_OF_RESOURCE was almost only used to note -ENOMEM situations.
Therefore, use -ENOMEM explicitely, and also print out warnings.

Deprecate unused CS_ error codes by replacing their definitions with
generic error messages, and removing them from the error_t lookup table.
Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
Instead of using own error or success codes, the PCMCIA code should rely on
the generic return values. Therefore, replace all occurrences of CS_SUCCESS
with 0.
