From: Robin Zhang Date: Sat, 9 Oct 2021 01:39:50 +0000 (+0000) Subject: net/i40e/base: fix potentially uninitialized variables X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=bc99971d1021ecc85280b9b98e84c9b5f4ba008e;p=dpdk.git net/i40e/base: fix potentially uninitialized variables The status of i40e_read_nvm_word is not checked, so variables set from this function could be used uninitialized. In this case, preserve the existing flow that does not block initialization by initializing these values from the start.
