+Subject: iwlwifi: mvm: Do not require PHY_SKU NVM section for 3168 devices
+
+The logic for checking required NVM sections was recently fixed in
+commit b3f20e098293 ("iwlwifi: mvm: fix NVM check for 3168
+devices"). However, with that fixed the else is now taken for 3168
+devices and within the else clause there is a mandatory check for the
+PHY_SKU section. This causes the parsing to fail for 3168 devices.
+
+The PHY_SKU section is really only mandatory for the IWL_NVM_EXT
+layout (the phy_sku parameter of iwl_parse_nvm_data is only used when
+the NVM type is IWL_NVM_EXT). So this changes the PHY_SKU section
+check so that it's only mandatory for IWL_NVM_EXT.
+
+Fixes: b3f20e098293 ("iwlwifi: mvm: fix NVM check for 3168 devices")
