the non-essential error messages to log variants so they
do not show up in dmesg.

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.

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.

Driver continues handling of MSI0 interrupt even if MHI register access
is not allowed. By doing so it calls the status call back and performs
early notification for the MHI client. This is not needed when MHI register
access is not allowed. Hence skip the handling in this case and return.

During fast suspend/resume, the power management states in MHI
can change to any error state. Allow for it by re-checking and
handling it such that pm states are not lost or over-written in
the process.

Some low priority event rings operate on a fast forwarding
mechanism where only the latest event is processed and the rest
are skipped. The recycle API only handles updating the
context write pointer in sequence which causes an out of bounds
doorbell issued to the device due to mismatched values. Add
another API to support handling updates for context write
pointer separately with the fast forwarding use case.

If time sync is requested by user space when endpoint is shutting
down dev_wake count gets incremented. This is causing assert when
shutdown API checks the dev_wake count and it is still non-zero.
Fix this issue by protecting time sync API and removal of time sync
under tsync_mutex. This helps to take care of a race condition when
time sync is requested while time sync remove in progress and also
makes sure that dev_wake count becomes zero when time sync remove
is done to prevent assert condition.

If extcon handler is present and dpdm regulator is absent, current
code starts USB state machine without checking usb role switch status.
This results into USB PHY being reset while ADSP firmware is performing
charger detection. This may result into wrong/invalid charger detection
instead of SDP causing no USB enumeration. Fix this issue by checking
usb role switch status before kicking USB state machine.

Currently, when sync_state re-votes to remove the init proxies, it
re-votes each voter for each BCM. However, each BCM is associated with
exactly one voter, so we only need to re-vote using the single voter
associated with the BCM. Not only does this improve performance by
removing unnecessary votes, but it can also fix stability issues when
the voter RSC isn't available yet.
