When application provided buffer size less than sockaddr_storage, then
kernel will overwrite some memory area which may cause memory corruption,
e.g.: in recvmsg case, let msg_name=malloc(8) and msg_namelen=8, then
usually application can call recvmsg successful but actually application
memory get

Thanks! Can you try the dbg patch attached? That will print more debugging

The return value of populate_vma_page_range() is consistent with
__get_user_pages(), and so is the function comment of return value.

When system suspended, we could explicitly disable clock to save power.
And we need save registers' state since it could be lost after power
off.
Implement PM which will:
1) Without CONFIG_PM, clock is always on after probe stage.
2) With CONFIG_PM, clock is off after probe stage.
3) Disable
