Subject: [PATCH] platform/x86: dell-rbtn: Add missing #include
Git-commit: e28f296ea155da36f710eb1f1173d8780fbac49d
Patch-mainline: v5.2-rc1
References: bsc#1051510

Building with W=1 complains:
  CC [M]  drivers/platform/x86/dell-rbtn.o
drivers/platform/x86/dell-rbtn.c:345:5: warning: no previous prototype for 'dell_rbtn_notifier_register' [-Wmissing-prototypes]
  345 | int dell_rbtn_notifier_register(struct notifier_block *nb)
      |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/platform/x86/dell-rbtn.c:371:5: warning: no previous prototype for 'dell_rbtn_notifier_unregister' [-Wmissing-prototypes]
  371 | int dell_rbtn_notifier_unregister(struct notifier_block *nb)
      |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The real problem is a missing include. Add it to keep dell-rbtn.c and .h in sync.
