wifi: iwlwifi: uninitialized variable in iwl_acpi_get_ppag_table()
[ Upstream commit 65c6ee90455053cfd3067c17aaa4a42b0c766543 ]
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.
