This patch corrects the support for MMCSD card detection
and read only feature for SoC DM355.

EVMDM355_ECP_VA4.pdf, from Spectrum digital, suggests that
Bit 2 and 4 should be checked for card detection. However
on the EVM, bits 1 and 3 gives this status, for MMC/SD
instance 0 and 1 respectively. The pdf also suggests that
Bit 1 and 3 should be checked for write protection. However
on the EVM bits 2 and 4 gives this status.

Current implementation is prone to races, this patch attempts to remove all
but one (in pcf50633_adc_sync_read).

The idea is that we need to guard the queue access only on inserting and
removing items. If we insert and there're no more items in the queue it
means that the last irq already happened and we need to trigger ADC
manually. If not, then the next conversion will be triggered by the irq
handler upon completion of the previous.

Using the default kernel "events" workqueue causes problems with
synchronous adc readings if initiated from some task on the same
workqueue.

I had a deadlock trying to use pcf50633_adc_sync_read from a
power_supply class driver because the reading was initiated from the
workqueue and it waited for the irq processing to complete (to get the
result) and that was put on the same workqueue.

Both drivers (rt2860 and rt3090) register themselves as "rt2860" on
loading the module.

In the very rare case of somebody having two cards in his machine, one
using rt3090 and the other one using the rt2860 driver, loading both
modules would be impossible, the second one will not be loaded as the
kernel will tell you that the driver is already registered.

This was also present with rt2870/rt3070 (with both driver registering
as "rt2870"), but the code has been merged to one driver recently.

The follwoing patch fixes this potential problem until merging of
rt2860/rt3090 code to a single driver.

The result of container_of should not be NULL.  In particular, in this case
the argument to the enclosing function has passed though INIT_WORK, which
dereferences it, implying that its container cannot be NULL.

follows:
