Subject: iwlwifi: always run the secured flow for family 8000
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c7583d7dd62d44a5e930d67e7e6b881a569a5561;p=linux-beck.git

iwlwifi: always run the secured flow for family 8000

In the new format the "CSS section" has the same TLV type
as the "mem section". So we need to run the secured flow
for all the 8000 products.
