(from https://patchwork.kernel.org/patch/10058587/)
proc->files cleanup is initiated by binder_vma_close. Therefore
a reference on the binder_proc is not enough to prevent the
files_struct from being released while the binder_proc still has
a reference. This can lead to an attempt to dereference the
stale pointer obtained from proc->files prior to proc->files
cleanup. This has been seen once in task_get_unused_fd_flags()
when __alloc_fd() is called with a stale "files".
The fix is to always use get_files_struct() to obtain struct_files
so that the refcount on the files_struct is used to prevent
a premature free. proc->files is removed since we get it every
time.

When doing WLAN SSR tests on Rome PCIe platform, system hang
is observed. After debugging, setting D3hot to PCIe link when
suspending leads to the hang.
Setting D3hot is a new change, which is added for Napier platform.
But this code path shares with legacy Rome platform. In previous
implementations for Rome PCIe platforms, setting D3hot to link
is not needed.
Fix is to set D3hot for Napier specific platforms.

Currently, Rconn is configured once in fg_hw_init() if it is not
configured already. However, if the driver loads the profile
later, it will overwrite the Rconn value configured during
fg_hw_init. To fix this problem, configure Rconn after handling
battery profile loading.
Usually the Rconn configuration is setup differently from what
the profile has for it. We check if the profile in SRAM is bit
to bit matching with the profile in device tree. We may come
across a mismatch for Rconn configuration and conclude that the
profile isn't matching. Fix this by initializing the Rconn
configuration in the profile read from device tree to the value
read from SRAM.

Fix the programming of DisplayPort SDP registers primarily related
to Audio enable sequence. This would fix potential issues caused by
read/append/write operations on SDP registers which might corrupt
the parity/data bytes. This would lead to audio issues since the DP
controller would treat the corrupt SDP information as invalid data.

Issue:
When total_steps is updated, after that, copy_from_user
fails with an error, then, i2c_reg_tbl is not allocated.
In this case, when calling msm_actuator_parse_i2c_params,
it lead to out-of-bound memory write.
Fix:
1) Assign total_steps to zero when error from copying.
2) Add NULL pointer check for i2c tbl.
