The return value of device resume function should be greater than
or equal to 0. Correct the conditional judgment to allow the return
value to be greater than 0. Otherwise, it can cause cti fail to
pass test sometimes.

Block layer RPM is enabled for the genernal UFS SCSI devices when they are
probed by their driver. However block layer RPM is not enabled for UFS
well-known SCSI devices.
As UFS SCSI devices have their corresponding BSG char devices, accessing
a BSG char device via IOCTL may send requests to its corresponding SCSI
device through its request queue. If BSG IOCTL sends a request to a
well-known SCSI device when hba is not runtime active, due to block layer
RPM is not eanbled for the well-known SCSI devices, hba, which is at the
top of a scsi device's parent chain, shall not be resumed, then unexpected
error would happen.
This change enables block layer RPM for the well-known SCSI devices, so
that block layer can handle RPM for the well-known SCSI devices just like
for the general SCSI devices.

On Lahaina, both VDD_GFX and VDD_MMCX support LowSVS as the minimum
non-OFF level. Therefore regulator_set_voltage() calls are redundant
and can be safely removed.
Commit f8702f9e4a ("regulator: core: Use ww_mutex for regulators
locking") introduced a call to mutex_lock(®ulator_list_mutex)
inside of regulator_lock_dependent(). This additional locking allows
deadlock to occur for regulator devices whose regulator_ops callback
functions internally call consumer regulator framework API functions
(e.g. regulator_enable(), regulator_disable(), or regulator_set_voltage()).
For short term remove all regulator_set_voltage() calls in the
gdsc-regulator driver as a short term partial workaround for regulator
framework deadlock issue.

Driver defers processing of BW scaling event if PM state is not in
M0. This delays the BW scaling to take effect. Fix this issue by
resuming the device if it was suspended state and assert wake DB.
After changing the BW of the link de-assert the wake DB.

The mhi_process_cmd_completion function reads cmd channel id from
cmd_pkt using MHI_TRE_GET_CHID, the value is under the control of MHI
devices and can be any value between 0 and 255. However the max channel
is defined in device tree file and it is usually smaller than 255. This
can cause out of bound access to the channel array. Fix this by checking
the channel id received in cmd ring against the max channel allowed on
target.

It is possible that the write offload worker gets a chance to
run after PCIe link is handed off to DRV subsystem. DRV
subsystem can enter L1SS sleep while work handler is trying to
access MHI register. This results into NOC error. Fix this
issue by flushing work before handing off PCIe link to DRV
subsystem or link enters D3 cold.

When PCIe endpoint enters L1SS sleep and mhi client on Host tries to
queue a transfer request endpoint takes more than 6ms to come back to
L0 state. This can cause CPU stall if MHI register write is followed
by a write memory barrier. This can cause other tasks to get blocked.
In order to prevent this add register write offload API
mhi_write_reg_offload() which would queue the write and handle write
request from worker thread in AMSS execution environment.

Currently MHI_ASSERT causes kernel panic in debug mode.
In performance mode it just prints warning and continues.
This can cause memory over-read, out of bound memory read.
All the places driver is asserting need to result into a
kernel panic to root cause the issue and prevent unwanted
memory access.
