commit 165a5e22fafb "block: Move bdi_unregister() to del_gendisk()"
added disk->queue dereference to del_gendisk(). Although del_gendisk()
is not supposed to be called without disk->queue valid and
blk_unregister_queue() warns in that case, this change will make it oops
instead. Return to the old more robust behavior of just warning when
del_gendisk() gets called for gendisk with disk->queue being NULL.

There is one variable defined in mmc_card, which
is not being used anywhere. Also it is wrongly
being freed from mmc_remove_card and causing
"double kfree" related issues.
To handle this, remove unused cached_ext_csd variable.

Currently pinctrl is obtained after it is used to obtain
strobe_enable and strobe_disable states. This is incorrect and
needs to be fixed. Also, when the switch device is disabled, the
pinctrl configuration for GPIO that drives the LED output is
selected only when the brightness or current is set to a non-zero
value in flash device.
To keep it simple, move the pinctrl configuration for GPIO that
drives the LED output (e.g. flash LED3) to the switch device so
that both flash and torch device need not have to control it.
Also, fix the pinctrl configuration for GPIOs that are used to
drive flash LED3 output on both 8998 and 660 for functional
correctness.

When an error is found during probe especially before registering

On MSM8998, SDR104 mode might be unstable causing CRC error on
the interface. So we need a workaround which would skip printing register
dumps on CRC errors and also downgrade bus speed mode to SDR50/DDR50 in
case of continuos CRC errors. This patch enables "qcom,sdr104-wa" property
to enable this workaround.

UHS-I SD cards support SDR104 mode which runs the SD card interface
clock upto 208 MHz. But we may see repeated CRC errors in SDR104
with some SDCC controllers. If this happens, this change would
reinit the card to lower speed (SDR50) hoping that CRC error
rate would reduce at lower clock speed (100MHz for SDR50).

If Ultra High Speed SD card supports both SDR50 and DDR50 modes then
this change will give preference to SDR50 over DDR50 mode as it seems
to be more reliable for board designs. While we are doing this, this
change also fixes some indentation issues in the function we are have

Commit 6cd18e711d "block: destroy bdi before blockdev is
unregistered." moved bdi unregistration (at that time through
bdi_destroy()) from blk_release_queue() to blk_cleanup_queue() because
it needs to happen before blk_unregister_region() call in del_gendisk()
for MD. SCSI though will free up the device number from sd_remove()
called through a maze of callbacks from device_del() in
__scsi_remove_device() before blk_cleanup_queue() and thus similar races
as described in 6cd18e711d can happen for SCSI as well as reported by
Omar [1].
Moving bdi_unregister() to del_gendisk() works for MD and fixes the
problem for SCSI since del_gendisk() gets called from sd_remove() before
freeing the device number.
This also makes device_add_disk() (calling bdi_register_owner()) more
symmetric with del_gendisk().
