bam_dmux_write() function modifies the state of a skb via skb_push(), but
if a later allocation fails, the state of the skb is not reverted to the
pre skb_push() state.
The error returned to the caller as a result of the allocation failure gets
propagated to the TCP/IP framework, which re-schedules a retry of the skb
at a later time. if enough retries occur due to allocation failures,
causes the assertion in skb_push() to fail.
If a later allocation fails, revert the skb buffer state to pre skb_push()
by calling skb_pull().

blk_rq_map_sg() function merges the physically contiguous pages to use same
scatter-gather node without checking if their page descriptors are
contiguous or not.
Now when dma_map_sg() is called on the scatter gather list, it would
take the base page pointer from each node (one by one) and iterates
through all of the pages in same sg node by keep incrementing the base
page pointer with the assumption that physically contiguous pages will
have their page descriptor address contiguous which may not be true
if SPARSEMEM config is enabled. So here we may end referring to invalid
page descriptor.
Following table shows the example of physically contiguous pages but
their page descriptor addresses non-contiguous.
-------------------------------------------
| Page Descriptor | Physical Address |
------------------------------------------
| 0xc1e43fdc | 0xdffff000 |
| 0xc2052000 | 0xe0000000 |
-------------------------------------------
With this patch, relevant blk-merge functions will also check if the
physically contiguous pages are having page descriptors address contiguous
or not? If not then, these pages are separated to be in different
scatter-gather nodes.

When the EHCI controller is removed using platform_device_del(),
the PM disable_depth counter is decremented once by the driver
core. Thus the driver's remove callback additionally calling
pm_runtime_disable() is leading to an unbalanced counter since
pm_runtime_enable() call happens only once when platform_device_add()
calls the probe callback. Fix this by removing the extraneous
pm_runtime_disable().

Flushing and disabling all endpoints during disconnect in controller
driver is simply wasteful and unnecessary. Flushing endpoints before
notifying disconnect to composite driver will have side effects too.
The active endpoints will be disabled by function drivers when they
notified about disconnect.
The current code use 100 msec timeout for flush operation. If controller
driver flush and disable all endpoints, the worst case timeout will be
added up to several seconds. This is leading to watch dog timeout.

Currently completion of endpoint flush operation is checked after
setting that endpoint bit with ENDPTFLUSH register and polling the
same to get it clear. It has been observed that sometime this flush
operation takes huge amount of time which results into watchdog
timeout issue due to this busy loop without any time-out. Hence add
time-out of 100ms for endpoint flush operation completion and also
add 100us delay before checking ENDPTFLUSH register for endpoint bit
clear or not.
Also print important usb status register and flushed endpoint dtds
at the time of issue.

If the high watermark is exceeded, then msm_smux_write() will return
-EAGAIN and then rmnet_xmit() will return NETDEV_TX_BUSY to have the
TCP/IP stack reschedule the packet. In the case where the high
watermark is hit, but not exceeded, then the function improperly returns
NETDEV_TX_BUSY resulting in the packet being sent a second time. Since
the packets are deleted in the write-done notification, the second
transmit will result in either an access-after-delete or a double-delete
crash.
Remove check for high-water mark hit in the transmit function since it
is handled by a high-watermark event from SMUX already.

DCD would fail with ACA-dock and ACA-A + HS/FS device. Use 750 msec
