     makefile: correctly sed paths
-    
+
     The default Makefile for tlp makes a mess with catenating `DESTDIR` to
     everything, but then not actualy using the catenated (_ prefixed)
     variables to sed it's `.in` files.
-    
+
     This patch makes sure that it correctly sets the paths, taking `DESTDIR`
     in account where it makes sense (e.g. /bin where we want $out/bin) but
     not where it doesn't (/etc/tlp.conf should be just that).
-    
+
     The reason DESTDIR is used at all, as opposed to the more appropriate
     PREFIX, is covered in the nix formula, and is (also) due to the Makefile
     being a bit "different."

     tlp-sleep.service: reintroduce
-    
+
     This patch reintroduces tlp-sleep as a systemd unit as opposed to a
     systemd system-sleep hook script. This is due to the recommendation by
     systemd itself to not use the hook scripts. As per the manual:
-    
+
     > Note that scripts or binaries dropped in /usr/lib/systemd/system-sleep/
     > are intended for local use only and should be considered hacks. If
     > applications want to react to system suspend/hibernation and resume,
     > they should rather use the Inhibitor interface[1].
