stable inclusion from stable-v6.6.33 commit 888b03fcd122ceccb728899d397007eb4a9a8d8a category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAD6H2
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit bb7b3c8e7180f36de75cdea200ab7127f93f58cc ]
Support for fhctl clocks in apmixedsys was introduced at a later point and to this moment only one mt6795 based platform has a fhctl DT node present. Therefore the fhctl support in apmixedsys should be seen as optional and not cause an error when it is missing.
Change the message's log level to warning. The warning level is chosen so that it will still alert the fact that fhctl support might be unintentionally missing, but without implying that this is necessarily an issue.
Even if the FHCTL DT nodes are added to all current platforms moving forward, since those changes won't be backported, this ensures stable kernel releases won't have live with this error.
