Sergey noticed a small but fatal mistake in __tty_insert_flip_char,
leading to an oops in an interrupt handler when using any serial

The problem is that I accidentally took the tty_buffer pointer
before calling __tty_buffer_request_room(), which replaces the
buffer. This moves the pointer lookup to the right place after
allocating the new buffer space.

MDSS represents the top level wrapper that contains MDP5, DSI, HDMI and
other sub-blocks. W.r.t device heirarchy, it's the parent of all these
devices. The power domain of this device is actually tied to the GDSC
hw. When any sub-device enables its PD, MDSS's PD is also enabled.
The suspend/resume ops enable the top level clocks that end at the MDSS
boundary. For now, we're letting them all be optional, since the child
devices anyway hold a ref to these clocks.
Until now, we'd called a runtime_get() during probe, which ensured that
the GDSC was always on. Now that we've set up runtime PM for the children
devices, we can get rid of this hack.
Note: that the MDSS device is the platform_device in msm_drv.c. The
msm_runtime_suspend/resume ops call the funcs that enable/disable
the top level MDSS clocks. This is different from MDP4, where the
platform device created in msm_drv.c represents MDP4 itself. It would
have been nicer to hide these differences by adding new kms funcs, but
runtime PM needs to be enabled before kms is set up (i.e, msm_kms_init
is called).

Requests for assigning/freeing SMP blocks by planes are collected during
the atomic check phase, and represented by mdp5_smp_state's 'assigned'
and 'released' members.
Once the atomic state is committed, these members are reset to 0,
indicating that the existing configuration satisfies all the planes.
Future atomic commits will copy the old mdp5_smp_state, and the 'assigned'
and 'released' members would be updated only if there was a change in
the plane configurations.
When we disable and re-enable display, we lose the values we wrote to the
SMP registers, but the code doesn't program the registers because there
isn't any change in mdp5_smp_state.
Fix this by writing to the registers irrespective of whether there was
a change in SMP state or not. We do this by keeping a cache of the
register values, and write them every time we commit a state.

Enable rudimentary runtime PM in the HDMI driver. We can't really do
agressive PM toggling at the moment because we need to leave the hpd

enable/disable paths, and the HDMI connector's detect() op.

mdp5_enable/disable calls are scattered all around in the MDP5 code.
Use the pm_runtime_get/put calls here instead, and populate the
runtime PM suspend/resume ops to manage the clocks.
About the overall design: MDP5 is a child of the top level MDSS
device. MDSS is also the parent to DSI, HDMI and other interfaces. When
we enable MDP5's power domain, we end up enabling MDSS's PD too. It is
only MDSS's PD that actually controlls the GDSC HW. Therefore, calling
runtime_get/put on the MDP5 device is like just requesting a vote to
enable/disable the GDSC.
Functionally, replacing the clock enable/disable calls with the RPM API
can result in the power domain (GDSC) state being toggled if no other
child isn't powered on. This can result in the register context being lost.
We make sure (in future commits) that code paths don't end up configuring
registers and then later lose state, resulting in a bad HW state.
For now, we've replaced each mdp5_enable/disable with runtime_get/put API.
We could optimize things later by removing runtime_get/put calls which
don't really need to be there. This could prevent unnecessary toggling of
the power domain and clocks.

ADG is registering fixed rate clock for audio_clkout, but it had not
been unregister clock when removing.
Salvator-X board is using ak4613 driver now, and it supports
hw_constraints from commit 907cd8809e ("ASoC: ak4613: add
hw_constraint rule for Sampling Rate").
And this calculation is using input clk. This ak4613 input clock is
ADG clkout on Salvator-X.
Because ADG had not been unregister clkout when unbinding, it receives
fixed rate clk register error when re-binding.
Thus, ak4613 can't get correct input clock, and hw_constraints will be
failed after re-binding.
This means Salvator-X board can't use sound after unbind/bind.

If an incoming packet undergoes XFRM crypto-offload, its secpath is
filled with xfrm_offload struct denoting offload information.
If the SKB is then forwarded to a device which supports crypto-
offload, the stack wrongfully attempts to offload it (even though
the output SA may not exist on the device) due to the leftover
secpath xo.
Clear the ingress xo by zeroizing secpath->olen just before
