Subject: ACPICA: Core: Always set GPIO VendorOffset
Patch-mainline: v4.13-rc1
Git-commit: cf45b58cd1aeeb324741c91e5e924d255fa4aafe
References: bsc#1117419

ACPICA commit 51a92f414de7af1f7f7524de3f61daf5413cac9f

Acpiexec gives this warning when resources containing GPIOs are extracted
using Resource command:

  **** Data mismatch in descriptor [00] type 8C, Offset 00000000 ****
  Mismatch at byte offset 13: is 00, should be 25
  **** Data mismatch in descriptor [01] type 8C, Offset 00000025 ****
  Mismatch at byte offset 13: is 00, should be 25

This happens because we do not set VendorOffset when doing resource to AML
conversion. Fix this by always setting VendorOffset.
