mmc: A few trivial changes for tmio-mmc

[PATCH 01/03] mmc: Let tmio-mmc use dev_name() with request_irq()
[PATCH 02/03] mmc: Remove const from tmio-mmc platform data V2
[PATCH 03/03] mmc: Balance tmio-mmc cell enable()/disable() calls

These patches contain a few trivial changes for the tmio-mmc driver.
Nothing out of the ordinary. Tested together with the sh_mobile_sdhi
mfd driver on a sh7724 Ecovec board.

Subject: [PATCH 01/03] mmc: Let tmio-mmc use dev_name() with request_irq()

From: Magnus Damm <[email protected]>

This change improves the /proc/interrupts output so the
irq number can be mapped to platform device on boards
with multiple tmio_mmc instances.

Subject: [PATCH 02/03] mmc: Remove const from tmio-mmc platform data V2

From: Magnus Damm <[email protected]>

This patch removes the const from the tmio-mmc
platform data parameter "hclk". Needed by the
SDHI driver.

V2 drops the SDHI bits to simplify merging.

Subject: [PATCH 03/03] mmc: Balance tmio-mmc cell enable()/disable() calls

From: Magnus Damm <[email protected]>

This patch adds cell->disable() calls to the tmio-mmc
probe() error handling and the remove() function.

Good news is that the linux-next issue seems solved now thanks to help
from Samuel Ortiz.

Nah, this patch is not urgent. It may also break other platforms, so I
prefer to resend it later.

Thanks,

This patch still doesn't apply due to linux-next changes which never
got merged into 2.6.33-rcX.

If you think it should go into 2.6.33 then please redo a patch against
mainline and we'll cheerily trash the problematic stuff in linux-next.
