perf: Treat attr.config as u64 in perf_swevent_init()

Trinity discovered that we fail to check all 64 bits of attr.config passed by user space,
resulting to out-of-bounds access of the perf_swevent_enabled array in
sw_perf_event_destroy().

Introduced in commit b0a873ebb ("perf: Register PMU
implementations").

ASoC: Avoid putting stream state to STOP when stream paused

When multiple Front-end are using the same Back-end, putting
the stream state for a Front-end to STOP will make the the Backend
stream to be released, when the front-end is paused. This will avoid
the Backend to be released (when another active front-end stream is
present).
Instead, put the stream state to PAUSED, which will keep the Back-end
ON.

ASoC: audio: Fix BE not disconnected even codec teardown

Scenario:
When FE1(LowLatency) comes in which opens BE1 and puts it in state
SND_SOC_DPCM_STATE_START. Similarly FE2(LPA) comes in with
connecting to same BE. Now FE2 is in SND_SOC_DPCM_STATE_PREPARE
state and waits for TRIGGER_START. Meanwhile FE1 is closed which
doesn't affect BE1 and FE2 which are connected.
Also, for FE2 pcm_close is called before TRIGGER_START itself.
In such a case, BE1 is not getting disconnected (afe_close is
not called) while Codec is teared down resulting in Slimbus
overflow.

Fix:
Whenever BE1 is found to be in SND_SOC_DPCM_STATE_START state
and FE1 being connected is not started yet, and close sequence
happens for this FE, then allow hw_free to happen for BE1 if
this is the only FE connected to this BE1. This allows BE to be
disconnected which calls afe_close then followed by Codec teardown
not resulting in any Slimbus overflows.

Advance hardware pointer by period size even if the packet

msm_serial_hs: Fix synchronization between ADM and UART Cores

With current UART Core programming sequence, it is seen that ADM
and UART Core are going out of sync in few usecases with regression.
It is fixed by using Force RxStale feature of UART Core from
set_termios() and sending discard flush to ADM which would terminate
currently queued UART RX CMD to ADM. Add termios_in_progress check
to make decision about what kind flush to send on receiving RxStale
interrupt. It makes set_termios() more reboust and also keeps ADM
and UART Core in-sync.

Add dma_in_flight to keep check of UART Rx CMD status and BUG_ON if
UART driver is trying to queue one more UART RX CMD to ADM as UART
driver re-uses same UART RX CMD.

This change also adds check of currently set uartclk rate and next
required uartclk rate for new baud rate. If both are same it would
not call clk_set_rate() to set same uartclk rate again.

UART baud rate change request (i.e. executing set_termios()) can come
asynchronously and time to program ADM hardware with queued CMD by ADM
driver is non-deterministic. It is required by UART driver to confirm
that queued RX CMD is programmed with ADM hardware before going with
requested baud rate change operation. Hence this change wait in
set_termios() for ADM driver to program queued RX CMD before going ahead
with baud rate. Otherwise ADM may encounter data bus error with UART RX
channel which is unrecoverable.

msm_serial_hs: Disable UART RxStale before Force RxStale in set_termios

There is possible race for handling normal RxStale event and Force
Rxstale event with UART Core, when Force RxStale is issued from
set_termios(). Hence on baud rate change request disable RxStale event
mechanism, and invoke Force RxStale. With RxStale event mechanism
disabled, Force RxStale still generates interrupt.

Fix possible race condition if before completion of previous UART RX CMD
flush, set_termios() request is received. With this case it is quite
possible that rx_tlet() queues one UART RX CMD with ADM driver and also
set_termios() queues one more UART RX CMD which would results with
queueing same UART RX CMD twice with ADM driver. With this device would
crash as the ADM driver will not be able to de-reference the second UART
RX CMD work. Hence add check in set_termios with rx.flush value as
FLUSH_DATA_READY which confirms that flush is initiated but it is not
completed and wait for rx.flush to become FLUSH_NONE which would happen
only once flush is completed and new UART RX CMD is being queued with ADM
driver.

Reduce waiting time for discard flush completion as it is already waited
for queued UART Rx CMD to be programmed with ADM hardware. Hence change
wait time out from 300 jiffies to 50 mseconds.

Add an API to get important UART core registers values which can be called
from error condition. Use the same when discard flush timeout happens with
set_termios(), when rx.dma_in_flight is not set with set_termios() and when
multiple UART RX CMD queueing condition is seen in msm_hs_start_rx_locked()
API.
