msm: peripheral-loader: Change IOMAP_SIZE from SZ_4M to SZ_1M

The ioremap call made for zeroing out trailing memory is currently
requesting for a 4M memory region. This is resulting in vmalloc
allocation failures on some platforms.
Instead, request for 1M memory locations and zero out the area
in smaller chunks to make this failure less probable.

mmc: core: Issue with voltage switch sequence

When a broken UHS-I card is inserted, the voltage switch sequence
fails as expected but the controller is left in bad state due to
which software request timeouts are observed for further commands.
Add mmc_power_cycle() for any failure in voltage switch so it will
also help reset the controller in addition to card.

media: Init the reserved fields of struct media_link_desc

struct media_link_desc is copy_to_user'ed as the return value of
MEDIA_IOC_ENUM_LINKS. When copying, the driver is omitting to initialise
the reserved fields.  This commit fixes that by initialising the
reserved fields to 0.

ASoC: dapm: Convert pin switches to use snd_soc_card

Since the addition of the non-CODEC control adds card controls like the
DAPM pin switch have been broken as they are expecting the private data
for the control to be the CODEC but it's now the card. Fix that for the
pin switches, an audit of other drivers is required.

ASoC: dapm: Use DAPM mutex for DAPM ops instead of codec mutex

It has now become necessary to use a DAPM mutex instead of the codec
mutex to lock the DAPM operations. This is due to the recent multi
component support and forth coming Dynamic PCM updates.

Currently we lock DAPM operations with the codec mutex of the calling
RTD context. However, DAPM operations can span the whole card context
and all components.

This patch updates the DAPM operations that use the codec mutex to
now use the DAPM mutex PCM subclass for all DAPM ops.

We also add a mutex subclass for DAPM init and PCM operations.

ASoC: dapm: lock mixer & mux update power with DAPM mutex

Both snd_soc_dapm_mux_update_power() and snd_soc_dapm_mixer_update_power() can
be called internally within DAPM core (with DAPM mutex held) and externally.

Provide some wrappers so that external users of both functions do not have to
remember to hold the DAPM mutex.
