Subject: iwlwifi: mvm: remove using max_duration in firmware API
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=65d66628500a40e2acbf1546af536801d65e0d14;p=deliverable%2Flinux.git

iwlwifi: mvm: remove using max_duration in firmware API

The firmware decided to not implement this API in this way,
so for now remove setting the field completely. This will
allow the firmware to change how to use this field later.
