From 65c6ee90455053cfd3067c17aaa4a42b0c766543 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 8 Feb 2024 13:17:31 +0300 Subject: [PATCH] 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.
