There might be cases during bootup when backlight cmds or ESD thread
sends DCS cmds to the panel when iommu attach is yet to happen. DSI
uses physical or virtual address based on the iommu_attached status
check. If iommu attach happens when the DCS cmds are using the
physical address, it would lead to SMMU page faults. Protect iommu
attach/detach and DCS cmd sending with an iommu_lock to avoid such
race conditions.

The policy engine should only request for a specific current
amount when establishing an explicit contract. When performing
a hard reset, suspend this by requesting 0 and only if it
was non-zero before, otherwise requesting the maximum may
invalidate the default current for non-PD cases.

There is a possibility of tasklet bottom half handler racing
with dwc3_msm_suspend(). As a result before disabling the dwc3
irq, dwc3 interrupts are fired and once the suspend routine
disables the clocks bottom half handler gets a chance to run
and tries to access dwc3 register resulting into un-clocked
register access. Since dwc3 interrupt is already running in
threaded irq context, interrupt can be directly handled in
same context and avoid this race.

amount (set via POWER_SUPPLY_PROP_CURRENT_MAX). Remove setting

The gadget mode notification to draw a specific current may
occur in context with interrupts disabled, however the charger
driver's implementation of power_supply_set_property() for
POWER_SUPPLY_CURRENT_MAX currently uses a mutex. Since
sleeping is disallowed in this case, instead schedule a
work function to do the call.

Commit 5ad6300524 ("genetlink: disallow subscribing to unknown
mcast groups") disallows userspace to subscribe to groups that don't
exist in kernel. As a result, communication between processes is
not possible unless they explicitly register a dummy group with the
kernel even if the communication is between userspace processes
only. NETLINK_USERSOCK cannot be used here since userspace processes
would require CAP_NET_ADMIN to receive multicast messages which
is available for priveleged processes only.
Fix this problem by reverting the change till a solution is
determined internally and upstream discussion.

Currently, if read pointer is behind write pointer and there
is not enough space toward the end of the ringbuffer for
new commands, then write pointer is being set to 0.
This is problematic, because it leads to the overwriting of
unexecuted commands with new commands at the start of the
ringbuffer. So, instead of setting the write pointer to 0,
look for space from the start of the ringbuffer up till the
read pointer and if there is room, update the write pointer
accordingly.
