Subject: iwlwifi: mvm: check minimum temperature notification length
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=be720d3fc049e14323f2ba637c053fe39d3e0157;p=linux-beck.git

iwlwifi: mvm: check minimum temperature notification length

This notification will be extended with extra data, so just
check that it has a minimum length, not the exact length;
we might later add handling for the extra fields added and
have more code to handle both versions.
