2021-02-04platform/x86: acer-wmi: Don't use ACPI_EXCEPTION()Hans de Goede1-2/+2
ACPI_EXCEPTION is only intended for internal use by the ACPICA code. ACPI_EXCEPTION was being used here to change the apci_status code into something human-readable, use acpi_format_exception() for this instead, which is the proper way to do this outside of ACPICA.

depends on With the #if IS_ENABLED(CONFIG_ACPI_PLATFORM_PROFILE), we get the following errors when thinkpad_acpi is builtin while CONFIG_ACPI_PLATFORM_PROFILE=m : drivers/platform/x86/thinkpad_acpi.c:10186: undefined reference to `platform_profile_notify' drivers/platform/x86/thinkpad_acpi.c:10226: undefined reference to `platform_profile_register' drivers/platform/x86/thinkpad_acpi.c:10246: undefined reference to `platform_profile_remove' This could be fixed by changing the IS_ENABLED to IS_REACHABLE, but I believe that it is better to just switch to using depends on. Using depends on ensures that platform-profile support is always available when thinkpad_acpi is build, hopefully leading to less confusing bug-reports about it sometimes not working.
