Public bug reported:
While testing the FFA support for EC secure service communication we
found an issue.
While copying the data back into ACPI FFH packet,it uses the request
length. The response data can be largerthan request length. The response
length can't be fetched in thelinux FFH handler function. We can copy
all the bytes fromffa_data.data. The ACPI AML code will only use the
required number bytes from this.
This patch will fix this patch:
Fixes: d0038ee ("NVIDIA: SAUCE: Add support for EC secure service
communication")
We will need the patch for linux nvidia 6.11 kernel and 6.14 kernel.
