Pierre Ossman 51ec92e295 mmc: use sysfs groups to handle conditional attributes
Suppressing uevents turned out to be a bad idea as it screws up the
order of events, making user space very confused. Change the system to
use sysfs groups instead.

This is a regression that, for some odd reason, has gone unnoticed for
some time. It confuses hal so that the block devices (which have the
mmc device as a parent) are not registered. End result being that
desktop magic when cards are inserted won't work.

Frank Seidel 882c49164d mmc: extend ricoh_mmc to support Ricoh RL5c476
This patch adds support for the Ricoh RL5c476 chip: with this

handled correctly when it sits on a RL5c476.

David Brownell 6e996ee8e7 at91_mci: use generic GPIO calls
Update the AT91 MMC driver to use the generic GPIO calls instead of the
AT91-specific calls; and to request (and release) those GPIO signals.

That required updating the probe() fault cleanup codepaths.  Now there
is a single sequence for freeing resources, in reverse order of their
allocation.  Also that code uses use dev_*() for messaging, and has less
abuse of KERN_ERR.

Likewise with updating remove() cleanup.  This had to free the GPIOs,
and while adding that code I noticed and fixed two other problems:  it
was poking at a workqueue owned by the mmc core; and in one (rare)
case would try freeing an IRQ that it didn't allocate.

happened to drag in that file via their <asm/dma-mapping.h>.

David Brownell 23fd50450a Fix compile while compiling drivers/mmc/host/mmc_spi.o with !BLOCK
Make sure the mmc_spi driver can build without CONFIG_BLOCK.
Issue noted by "Avuton Olrich" <avuton@gmail.com> and randconfig.

While that won't be a common configuration, sometimes embedded
boards use SDIO to interface WLAN or Bluetooth chips (vs some
parallel interface), and don't provide an MMC/SD socket for use
with flash memory cards.

Kay Sievers 7eff2e7a8b Driver core: change add_uevent_var to use a struct
This changes the uevent buffer functions to use a struct instead of a
long list of parameters. It does no longer require the caller to do the
proper buffer termination and size accounting, which is currently wrong
in some places. It fixes a known bug where parts of the uevent
environment are overwritten because of wrong index calculations.

Many thanks to Mathieu Desnoyers for finding bugs and improving the
error handling.

Pierre Ossman 77f1fd6ecd mmc: use correct unregister function for led trigger
We register a simple trigger so make sure we use the corresponding
unregister function.

(Also means we get a dummy function when triggers aren't compiled in)
