slim_ngd: Add NULL pointer check apart from error check

Check against NULL pointer after allocating
the memory for msm_slim_ctrl structure pointer
dynamically to avoid unexpected crashes.

Earlier this pointer is checked only for error
codes. In this patch NULL pointer check is also
added.

slimbus: initial overclocking of slimbus

Increase root freq from 11 (24.526MHz) to 31 max (27+MHz) which is the
largest it will take .Increase clock gear from 7 to 10 (max again)

This means SLIMbus will use its maximum potential to give the best audio
quality for the hardware. Takes advantage of both hardware and the mods
from zeroinfinity, also opening the door for more things that were
previously limited by this. Researched and experimented by ZeroInfinity
and Poondog

PM / wakeup: Use irqsave/irqrestore for events_lock

Jon Medhurst (Tixy) recently noticed a problem with the
events_lock usage. One of the Android patches that uses
wakeup_sources calls wakeup_source_add() with irqs disabled.
However, the event_lock usage in wakeup_source_add() uses
spin_lock_irq()/spin_unlock_irq(), which reenables interrupts.
This results in lockdep warnings.

The fix is to use spin_lock_irqsave()/spin_lock_irqrestore()
instead for the events_lock.

I think removing this is not a good idea after all.

Previous of this patch it would stutter the audio. With this separate work it will online cpu1 if the load justifies and so audio stutters are no more.""

mm: make is_vmalloc_addr lockless

is_vmalloc_addr currently takes the vmap_area_lock and walks
the list of vmalloc areas to determine if an address is actually
a vmalloc address. Unfortunately, the current locking structure
with vmap_area_lock does not disable irqs which means that it may
be possible to recusively take the vmap_area_lock if an irq occurs
while walking the tree list. Considering the list of possible
vmalloc vs. not vmalloc ranges is not going to change after bootup,
skip the tree walking and just keep a bitmap of which virtual
addresses are set aside for vmalloc and which are not.

USB: u_serial: Don't free usb_requests in gs_close and reuse them

Commit: 950a3a3 "USB: Gadget: u_serial: Freeing usb requests as a
part of gs_close" results in freeing requests and flushing the EP
on every port close even if USB connection is present. These requests
are allocated again on port open. Also, EP flush call may result in
unclocked access of USB hardware if USB BUS state was suspended at
the time of port_close. This patch fixes that and also addresses the
original issue of gs_open allocating usb requests on every port_open
by adding a condition to allocate USB requests in port open only if
they are not already allocated.

sync: signal pt before sync_timeline object gets destroyed

There is a race condition

Assume we have *one* sync_fence object, with *one* sync_pt
which belongs to *one* sync_timeline, given this condition,
sync_timeline->kref will have two counts, one for sync_timeline
(implicit) and another for sync_pt.

Assume following is the situation on CPU

Theead-1 : (Thread which calls sync_timeline_destroy())
  -> (some function calls)
   -> sync_timeline_destory()
    -> sync_timeline_signal() (CPU is inside this
function after putting reference to sync_timeline)

At this time Thread-2 comes and does following

Thread-2 : (fclose on fence fd)
> sync_fence_release() -> because of fclose() on fence object
 -> sync_fence_free()
  -> sync_pt_free()
   -> kref_put(&pt->parent->kref, sync_timeline_free);
    -> sync_timeline_free() (CPU is inside this because
this time kref will be zero after _put)

Thread-2 will free sync_timeline object before Thread-1
has finished its work inside sync_timeline_signal.

With this change we signals all sync_pt before putting
reference to sync_timeline object.
