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") +Signed-off-by: Dan Moulding <dmoulding@me.com> +--- + drivers/net/wireless/intel/iwlwifi/mvm/nvm.c | 3 ++- + 1 file changed, 2 insertions(+), 1 deletion(-) + +diff --git a/drivers/net/wireless/intel/iwlwifi/mvm/nvm.c b/drivers/net/wireless/intel/iwlwifi/mvm/nvm.c +index 46128a2a9c6e..e98ce380c7b9 100644 +--- a/drivers/net/wireless/intel/iwlwifi/mvm/nvm.c ++++ b/drivers/net/wireless/intel/iwlwifi/mvm/nvm.c +@@ -308,7 +308,8 @@ iwl_parse_nvm_sections(struct iwl_mvm *mvm) + } + + /* PHY_SKU section is mandatory in B0 */ +- if (!mvm->nvm_sections[NVM_SECTION_TYPE_PHY_SKU].data) { ++ if (mvm->trans->cfg->nvm_type == IWL_NVM_EXT && ++ !mvm->nvm_sections[NVM_SECTION_TYPE_PHY_SKU].data) { + IWL_ERR(mvm, + "Can't parse phy_sku in B0, empty sections\n"); + return NULL; +-- +2.25.0 + |
