Subject: iwlwifi: mvm: move all UMAC scan flags setting into the relevant function
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6f4dcc76e07bdf164a101db68a6b0398afe57afd;p=linux-beck.git

iwlwifi: mvm: move all UMAC scan flags setting into the relevant function

Clean the code a little by moving all the flags into the right
function.  Additionally, rename the function, since "common" is now
irrelevant.
