Add mdio_bus_id and phy_addr to access phy device
instead of scanning mdio bus. It will reduce time
cost during ethernet driver loading.

We observed an interrupt storm on that interrupt
even after the usb path is suspended.
So keep this interrupt disabled as long as the usb
path is suspended.
Note that since the current limit votes can come in
prior to interrupt registration, rerun the election
on the votable after interrupts are registered.

Start offset is not considered in cache operation logic,
due to which bytes at the end of payload might be stale.
Add logic to add offset to cache operation length
from start of buffer, to ensure correct cache operation.

On consecutive writes in bulk write API, ensure delay
is provided for atleast 100us between each soundwire
master write for WR_DONE status update and reflect
current register value. Also ensure delay in soundwire
master read is present after register address update
and before register value read.

Pointer from userspace is de-referenced before the command is checked.
This might cause a crash if the command being sent is not a valid command.
Hence changing the de-reference such that the pointer is accessed after
checking if a valid command is sent from the userspace.

We have observed race condition between inquiring the remote pd state and
indication call back execution. They run asynchronously so we have no
control on their concurrent execution. So to achieve mutual exclusion,
moving the portion of code which result in race condition to indication
acknowledgment routine. Indication acknowledgment is send in separate
thread context which will avoid race condition.

__list_lru_walk_one() acquires nlru spin lock (nlru->lock) for longer
duration if there are more number of items in the lru list. As per the
current code, it can hold the spin lock for upto maximum UINT_MAX entries
at a time. So if there are more number of items in the lru list, then

Fix this lockup by reducing the number of entries to be shrinked from the
lru list to 1024 at once. Also, add cond_resched() before processing the
lru list again.
