Subject: [PATCH 5.4 075/155] iwlwifi: mvm: fix non-ACPI function

From: Johannes Berg <johannes.berg@...el.com>

commit 7937fd3227055892e169f4b34d21157e57d919e2 upstream.

The code now compiles without ACPI, but there's a warning since
iwl_mvm_get_ppag_table() isn't used, and iwl_mvm_ppag_init() must
not unconditionally fail but return success instead.
