Delta battery SOC interrupt can fire during boot just after
registering the interrupts before disabling it through vote() on
delta_bsoc_irq_en_votable during driver probe. When this happens,
from the delta_bsoc interrupt handler, an attempt to disable the
interrupt can be made by fg_charge_full_update() if charge_done
is not set. This will in turn acquire the mutex lock of votable
while trying to do disable_irq() which needs synchronization.
Prevent this situation by using disable_irq_nosync() when
disabling the interrupts from votable callbacks.

Currently, wait for soc_update completion is attempted once again
only when the wait is interrupted. Try waiting again even when it
is timed out. This should help IMA_ATOMIC transactions go through
reliably.

In the case of gsi_free_inst() called, whole f_gst structure is freed.
GSI control related API like gsi_ctrl_dev_poll do not check if f_gsi
is freed or not, only check gsi_ctrl_port is NULL or not.
If GSI driver is opened by userspace, gsi_free_inst() is executed,
mark inst_exist to false but do not free instance structures and
deregister misc device until misc device is closed.
Besides, in the GSI control related API read/write/ioctl/poll,
check if GSI instance is freed or not.

This change starts using dl_max_packet_size value sent by host
as part of USB RNDIS init message communication. Using default
dl_max_packet_size value results into low throughput with more
data loss on host side as host side RNDIS can't support
de-aggregation (applicable for Linux Host RNDIS driver) or it
ignores received more data then host side RNDIS can handle. To
use fine tune dl_max_packet_size for better throughput, driver
selects minimum value between host supported dl_max_packet_size
and default size (i.e. 9216 bytes as RNDIS IN aggregation size).

Fix ordering of link creation between node->prev and prev->next in
osq_lock(). A case in which the status of optimistic spin queue is
CPU6->CPU2 in which CPU6 has acquired the lock.
tail
v
,-. <- ,-.
|6| |2|
`-' -> `-'
At this point if CPU0 comes in to acquire osq_lock, it will update the
tail count.
CPU2 CPU0
----------------------------------
tail
v
,-. <- ,-. ,-.
|6| |2| |0|
`-' -> `-' `-'
After tail count update if CPU2 starts to unqueue itself from
optimistic spin queue, it will find an updated tail count with CPU0 and
update CPU2 node->next to NULL in osq_wait_next().
unqueue-A
tail
v
,-. <- ,-. ,-.
|6| |2| |0|
`-' `-' `-'
unqueue-B
->tail != curr && !node->next
If reordering of following stores happen then prev->next where prev
being CPU2 would be updated to point to CPU0 node:
tail
v
,-. <- ,-. ,-.
|6| |2| |0|
`-' `-' -> `-'
osq_wait_next()
node->next <- 0
xchg(node->next, NULL)
tail
v
,-. <- ,-. ,-.
|6| |2| |0|
`-' `-' `-'
unqueue-C
At this point if next instruction
WRITE_ONCE(next->prev, prev);
in CPU2 path is committed before the update of CPU0 node->prev = prev then
CPU0 node->prev will point to CPU6 node.
tail
v----------. v
,-. <- ,-. ,-.
|6| |2| |0|
`-' `-' `-'
`----------^
At this point if CPU0 path's node->prev = prev is committed resulting
in change of CPU0 prev back to CPU2 node. CPU2 node->next is NULL
currently,
tail
v
,-. <- ,-. <- ,-.
|6| |2| |0|
`-' `-' `-'
`----------^
so if CPU0 gets into unqueue path of osq_lock it will keep spinning
in infinite loop as condition prev->next == node will never be true.
