Subject: mei: me: d0i3: move mei_me_hw_reset down in the file
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ebad6b945ee2e7e93454ba52030b93e08290317c;p=linux-beck.git

mei: me: d0i3: move mei_me_hw_reset down in the file

Move mei_me_hw_reset down in the source file to avoid
forward declarations when introducing d0i3 flow in the next patch.
