Currently, smb2 charger uses VBT_LT_CHG_RECHARGE_THRESH signal
from FG to enable auto recharge by default. Add support to
configure smb2 charger to use SOC_LT_CHG_RECHARGE_THRESH signal
from FG if needed.
This will enable charging to resume again when battery SOC drops
below the automatic recharge SOC threshold (configured in FG)
while charger is inserted and SOC goes down after the charge
termination had happened.

enable_irq() called before processing responses in work handler
which would lead to miss interrupt from video hardware sometimes.
An interrupt from video h/w will queue the work to work handler
but if work is already running the new work is not posted.
work handler has two parts, one, read all the messages from video h/w,
two, process the messages. queue work while processing messages
will miss reading the new messages from video h/w because
the queue work (as a result of interrupt from video h/w) will not
actually queue the work as work handler already running. Fix the
issue by enabling irq after processing all the responses to
makesure interrupt coming from video h/w after work handler
completed processing the messages.

Add support for the multimedia clock controller found on MSMFalcon

Fix GSI interrupt processing to make sure interrupt are
not missed. In order to achieve that interrupt should first be

If nlh->nlmsg_len is zero then an infinite loop is triggered because
'skb_pull(skb, msglen);' pulls zero bytes.
The calculation in nlmsg_len() underflows if 'nlh->nlmsg_len <
NLMSG_HDRLEN' which bypasses the length validation and will later
trigger an out-of-bound read.
If the length validation does fail then the malformed batch message is
copied back to userspace. However, we cannot do this because the
nlh->nlmsg_len can be invalid. This leads to an out-of-bounds read in

Fix this with better validation of nlh->nlmsg_len and by setting
NFNL_BATCH_FAILURE if any batch message fails length validation.

Plugging a Logitech DJ receiver with KASAN activated raises a bunch of
out-of-bound readings.
The fields are allocated up to MAX_USAGE, meaning that potentially, we do
not have enough fields to fit the incoming values.
