ASoC: WCD9304: Add the compander support to wcd9304

The compander system is intended to increase the dynamic
range of an input signal. But for the wcd9304 codec,
this feature is to use companding in a novel way in the DAC
converter path to increase the signal noise ratio.
The change is to add the compander support to wcd9304
codec. The dynamic compander enable/disable during stream
playback is not supported.

msm: kgsl: Protect the mem_entry list during deletion

Use the spinlock to prevent corruption of the mem_entry list during
deletion. Otherwise the mem_entry list may be modified by another
thread at the same time resulting in memory corruption.

ci13xxx_udc: Acquire spinlock before calling ep_nuke()

The commit b0ad433 (USB: ci13xxx_udc: Fix kernel panic during
composition switch) adds ep_nuke() function in gadget_stop_activity().

_ep_nuke() releases and re-acquires spinlock on every entry of the
function. Acquiring spinlock before calling _ep_nuke() is necessary,
else it may end up in unlocking the lock twice, as it is already
unlocked before calling _ep_nuke(), which may lead to crash.

Hence, acquire spinlocks before calling _ep_nuke() function.

media: dvb: Protect against removing all PIDs from an active filter

When TS filter is active (running), it is not allowed to remove
all PIDs associated with the filter; The filter state would be
invalid and as such may result in unexpected behavior while
performing runtime operations on the filter.

USB: ci13xxx_udc:  Retire pending requests while flushing an endpoint

Rmnet and dun function drivers are designed to start fresh upon MODEM
restart.  The current code is flushing endpoints without freeing
requests.  New requests are allocated again after MODEM is powered up.
All accumulated requests are freed only upon cable disconnect.  If
MODEM is restarted multiple times without disconnecting the cable, we
are running low memory issues.

A pending request can not be freed without dequeuing it.  Dequeuing
all requests in a loop is a heavy operation and involves changing
multiple function drivers.  All pending requests are retired upon
disabling an endpoint.  But an endpoint can not be disabled in
configured state.  Hence retire pending requests while flushing an
endpoint.

gpu: ion: Do fallback when allocating large sizes

The preferred allocation of memory for kernel data structures in
ION is to use kmalloc. This is mainly for performance reasons. However,
we are not guaranteed to be able to allocate large sizes. So to keep
the code performing well and at the same time allow for larger allocations,
implement a fallback mechanism for allocation of memory for ION kernel data
structures.
