Subject: platform/x86: asus-wmi: Fix thermal profile initialization
From: Armin Wolf <W_Armin@xxxxxx>
commit b012170fed282151f7ba8988a347670c299f5ab3 upstream.
When support for vivobook fan profiles was added, the initial
call to throttle_thermal_policy_set_default() was removed, which
however is necessary for full initialization.
Fix this by calling throttle_thermal_policy_set_default() again
when setting up the platform profile.
AFAIK the offending commit was never backported to the 6.6-stable tree, so this commit
is mot necessary here since the original call to throttle_thermal_policy_set_default() is
still present.
Thanks, Armin Wolf
