From: Sara Sharon Date: Sun, 8 Jan 2017 14:45:46 +0000 (+0200) Subject: iwlwifi: adjust NVM parsing APIs for new a000 method X-Git-Tag: v4.12-rc1~129^2~65^2^2 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=291084951825e1efca081926b10bf3ff7e872476;p=karo-tx-linux.git iwlwifi: adjust NVM parsing APIs for new a000 method In a000 devices we will get all nvm data from the firmware, and can save most of the parsing. Export two APIs that op mode will still use. Adjust API of init_sbands to be independent of NVM file structure so it can be used by op mode as well.
