In function ufs_qcom_dbg_testbus_cfg_write(), the global
variable ufs_qcom_host (host) is not protected by lock.
In function ufs_qcom_testbug_config(), we are checking this
variable in switch case and there is possibility of race
condition while accessing host variable in both of these
functions. This change fixes the possible race scenario
using spin_lock on host_lock.

Create new function ext4_issue_zeroout() to zeroout contiguous (both
logically and physically) part of inode data. We will need to issue
zeroout when extent structure is not readily available and this function
will allow us to do it without making up fake extent structures.

qcedev_sha_req_cb() is only called by _sha_complete() during sha
operation, and will copy byte_count value from authdata array.
This array size is two, and only contains two byte_count value
that are used for sha operation. So make change to only copy the
first two elements from this array.

Currently, charge_counter is based off CC_SOC_SW which is based
off coulomb counter. However, there could be some accumulation
of error due to inaccuracy in ADC over time. This can potentially
affect the accuracy of charge_counter. To overcome this, prime
CC_SOC_SW during discharging based off battery SOC and to a full
value during charge termination.
While at it, expose the charge_counter_shadow property based off
battery SOC for comparison.

When SOC is held @ 100% after charge termination, charge_full
flag is cleared only when the monotonic SOC drops below recharge
SOC threshold. This can cause the flag to be held for a long time
when the charger is removed. Fix this by clearing charge_full
flag when charging status had changed from FULL.

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.

only when the wait is interrupted. Try waiting again even when it

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).
