Build failure in linux-next: implicit declaration of acpi_has_method

[Venkat Rao Bagalkote <venkat88@linux.ibm.com>]

Greetings!!!

IBM CI has reported a build failure on linux-next repo.

Failures:

drivers/bluetooth/btintel_pcie.c: In function 
‘btintel_pcie_acpi_reset_method’:
drivers/bluetooth/btintel_pcie.c:2309:14: error: implicit declaration of 
function ‘acpi_has_method’; did you mean ‘acpi_has_watchdog’? 
[-Werror=implicit-function-declaration]
  2309 |         if (!acpi_has_method(handle, "_PRR")) {
       |              ^~~~~~~~~~~~~~~
       |              acpi_has_watchdog


The function acpi_has_method() lacks a stub definition in 
include/linux/acpi.h
for the !CONFIG_ACPI case, unlike other ACPI utility functions.


Below diff fixes the build failure.

Please let me know, If this looks good, I can submit a formal patch.
