Subject: [PATCH 2/2] wifi: iwlwifi: uninitialized variable in
iwl_acpi_get_ppag_table()
This is an error path and Smatch complains that "tbl_rev" is uninitialized
on this path. All the other functions follow this same patter where they
set the error code and goto out_free so that's probably what was intended
here as well.
Fixes: e8e10a37c51c ("iwlwifi: acpi: move ppag code from mvm to fw/acpi")
