Update vblank reference counts via the exposed sde_crtc_vblank
function, rather than attempting to zero it on the side during
CRTC disable operations. This allows the power voting to be
updated correctly based on the vblank reference count value.

Move the power resource request/release from the sde kms layer
into the CRTCs so that proper accounting for suspend/resume

made as long while the CRTC's vblank request ref count is not
zero and the driver is not in a suspended state.

true otherwise. But KTM return value check is wrong and leads to
no secure watchdog bite call from KTM for all targets.

'commit 9021973bac ("coresight-remote-etm: Adds missing lock to avoid

needed as we are waiting inside it for a response of request made
remote_etm_enable => qmi_send_req_wait() which already holds lock
'drvdata->mutex'.
So, adding 'drvdata->mutex' inside remote_etm_rcv_msg() adds wait for
the lock and due to which not able to ack the response got which results
in timeout error qmi_send_req_wait().
This patch fixes the above mentioned issue by removing the lock added in

The last_pet variable is set in suspend callback and during
pet_watchdog() and is printed when watchdog bark handler gets
called. This variable does not represent exact last pet time in
cases where non secure bark occurs before system could pet the
watchdog upon wakeup event from low power mode. Reset the
watchdog during msm_watchdog_resume() and update last_pet
variable so that watchdog bark messages will represent latest
info.
This commit also adds memory barrier after resetting watchdog in
msm_watchdog_suspend(). This will make sure watchdog writes are
complete before proceeding further.

So far, dwc3 has always missed request->zero
handling for every endpoint. Let's implement
that so we can handle cases where transfer must
be finished with a ZLP.
Note that dwc3 is a little special. Even though
we're dealing with a ZLP, we still need a buffer
of wMaxPacketSize bytes; to hide that detail from
every gadget driver, we have a preallocated buffer
of 1024 bytes (biggest bulk size) to use (and
share) among all endpoints.

When the Camera application exercises the V4L2 ioctl operations, CPP
driver would attempt to the copy user space buffer contents into the
internal kernel buffer. If an invalid length of the user space buffer
is passed onto the driver, it could trigger buffer overflow condition.
Thus, fix this by copying user space buffer contents into kernel space
buffer of the driver for further processing, only after checking for
proper length of user space buffer.
