This separates the kref for ion handles into two components.
Userspace requests through the ioctl will hold at most one
reference to the internally used kref. All additional requests
will increment a separate counter, and the original reference is
only put once that counter hits 0. This protects the kernel from
a poorly behaving userspace.

Commit <be0960374> ("scsi: ufs: scale up the gear in 2 steps") introduced
a bug where we would not scale up the gear to HS-G3 if
UFS_DEVICE_QUIRK_HS_G1_TO_HS_G3_SWITCH quirk isn't enabled for UFS device.
Fix this by allowing HS-G3 scaling irrespective of quirk state.

For branch clocks having aggr_sibling_rates flag as set, get_rate()
always returns the parents rate despite the branch clocks prepare
status. Fix the same by adding a check for branch prepare status
and aggr_sibling_rates flag value.

This enables 128 bit matching in ip6tables to help
optimize cases where there is no match required.
This shows a rough improvement of 40Mbps in a UDPv6
downlink test using iperf.

iptables matching for ipv6 always has a mask if an address is
specified for match. Adding a check for mask prior to that
helps to improve performance as it avoids the masked comparison.
This is achieved by defining a new feature IP6_NF_IPTABLES_128
which allows to perform 128 bit arithmetic while matching.

OLEDB driver needs to configure the PBS RAM sequence for
disabling the OLEDB pull down during the module disable.
Add it for PM660A.

On SSR scenario disable statuses for modem producer pipes.
Since modem is not up these statuses are redundant and are
not read by any EE.

OLEDB_SPARE_CTL register bit is set by the PBS during the display enable
and is used during the display suspend to trigger the PBS event.
Hence, move clearing of the OLEDB_SPARE_CTL register to regulator disable.
Also enable the force_pd_ctl only for DRAX-A revisions <=2.0.

process descriptor before issuing a signal to it while
subsystem restart is performed. This fix avoids accessing
of cleaned-up process descriptor's fields.
