[Cause of problem]
Accoring to the factory's stress test,the system will hang when the sim1+sim2+sd card in quickly insert and remove.
the system willreturn to normall after long press in boot keyboard.
[Solution]
The jitter of Cato is analyzed ,it is found that 200ms dedithering time set in the original is too little We change to 1.5S .
after testing, It was found that the change decreased to one in ten thousand.
[Side-effect]
If you insert the sdcard, will longer 1.3s than old config to see the sdcard icon

[Cause of problem]
Logic of NFC HAL: after sending the commands, HAL will pull down NFC
GPIO0 and notify NFC chip that it can sleep after wait for 1 second.
If power key is pressed, AP will sleeps quickly, so that the 1 second timeout processing of NFC
HAL can not be executed, so the NFC chip cannot sleep.
But there is no issue if enter sleep is by screen auto time-out
[Solution]
In the NFc driver suspend call, check whether the hal has pulled down
NFC GPIO0. If not, prevent the system go to sleep 1 second.
[Side-effect]
None (The time to prevent go to sleep is 1 second, this can be ignored
in power consumption)

29bc22ac5e5b ("binder: use euid from cred instead of using task").
Setting sender_euid using proc->cred caused some Android system test
regressions that need further investigation. It is a partial
reversion because subsequent patches rely on proc->cred.

commit 52f88693378a58094c538662ba652aff0253c4fe upstream.
Since binder was integrated with selinux, it has passed
'struct task_struct' associated with the binder_proc
to represent the source and target of transactions.
The conversion of task to SID was then done in the hook
implementations. It turns out that there are race conditions
which can result in an incorrect security context being used.
Fix by using the 'struct cred' saved during binder_open and pass
it to the selinux subsystem.

Set a transaction's sender_euid from the 'struct cred'

Afer Zram backing dev setuped, zram will be treated as a ASYNC IO
swap device, no longer SYNC IO device, because WB pages do have IO
operation on swap in, so the optimization on skiping swapcache
for fast swap device will no longer be applyed on such case.
Now we refactor this optimization, skip the swapcache by checking
SYNC IO state on each swap page via ioctl. Reuse ioctl because we
should not break the GKI.
