Julia Lawall 01fa235c6e mmc: sdricoh_cs: constify mmc_host_ops structures
The mmc_host_ops structure is only stored in the ops field of an
mmc_host structure, which is declared as const.  Thus the mmc_host_ops
structure itself can be const.

Done with the help of Coccinelle.

Colin Ian King 675a7da857 mmc: sdricoh_cs: remove redundant check if len is non-zero
At the end of either of the read or write loops len is always zero
and hence the non-zero check on len and return of -EIO is redundant
and can be removed.

Markus Elfring 1856de3d3e mmc: sdricoh_cs: Less checks in sdricoh_init_mmc() after, error detection
This issue was detected by using the Coccinelle software.

Two pointer checks could be repeated by the sdricoh_init_mmc() function
during error handling even if the relevant properties can be determined
for the involved variables before by source code analysis.

* This implementation detail could be improved by adjustments
  for jump targets according to the Linux coding style convention.

* Drop an unnecessary initialisation for the variable "mmc" then.

Markus Elfring c48c5d580e mmc: sdricoh_cs: Delete unnecessary variable initialisations
These variables will eventually be set to an appropriate value a bit later.
* host
* iobase
* result

Thus let us omit the explicit initialisation at the beginning.

Ulf Hansson b2822d3725 mmc: sdricoh_cs: Move away from using deprecated APIs
Suspend and resume of cards are being handled from the protocol layer
and consequently the mmc_suspend|resume_host APIs are deprecated.

This means we can simplify the suspend|resume callbacks by removing the
use of the deprecated APIs.

Dominik Brodowski 1ac71e5a35 pcmcia: convert pcmcia_request_configuration to pcmcia_enable_device
pcmcia_enable_device() now replaces pcmcia_request_configuration().
Instead of config_req_t, all necessary flags are either passed as
a parameter to pcmcia_enable_device(), or (in rare circumstances)
set in struct pcmcia_device -> flags.

With the last remaining user of include/pcmcia/cs.h gone, remove
all references.

Remove cs_types.h which is no longer needed: Most definitions aren't
used at all, a few can be made away with, and two remaining definitions
(typedefs, unfortunatley) may be moved to more specific places.

Matt Fleming 1a13f8fa76 mmc: remove the "state" argument to mmc_suspend_host()
Even though many mmc host drivers pass a pm_message_t argument to
mmc_suspend_host() that argument isn't used the by MMC core.  As host
drivers are converted to dev_pm_ops they'll have to construct
pm_message_t's (as they won't be passed by the PM subsystem any more) just
to appease the mmc suspend interface.

We might as well just delete the unused paramter.
