From d4f1a50ca998420e27f904128a8dac5f69c291ed Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 12 Jun 2023 18:51:10 +0300 Subject: wifi: iwlwifi: unify checks for HW error values The hardware, depending on which part fails or times out, returns 0xA5A5A5A. or 0x5A5A5A5. with the lowest 4 bits encoding some further reason/status. However, mostly we don't really need to care about the exact reasons, so unify the checks for this to avoid hardcoding those magic values all over the driver.
