[origin tree build failure] [PATCH] input: Fix build failures caused by Kconfig Winbond WPCD376I Consumer IR hardware driver Kconfig entry

[Ingo Molnar <mingo@elte.hu>]

( ob-sidenote: Andrew, i did not find the patch for commit 16af5bb on 
  lkml and it's now upstream. It would be highly useful if you Cc:-ed 
  lkml with submitted patches like all maintainers do, so that patterns 
  can be grepped for and discussions can be continued quickly instead of 
  created anew. It would also significantly increase the S/N ratio of 
  lkml. Thanks! )

Subject: [PATCH] input: Fix build failures caused by Kconfig Winbond WPCD376I Consumer IR hardware driver Kconfig entry

-tip testing found this build failure:

  drivers/built-in.o: In function `apanel_remove':
  apanel.c:(.text+0x56e852): undefined reference to `led_classdev_unregister'
  drivers/built-in.o: In function `apanel_probe':
  apanel.c:(.text+0x56eae3): undefined reference to `led_classdev_register'
  drivers/built-in.o: In function `acpi_fujitsu_hotkey_add':

  winbond-cir.c:(.devinit.text+0x5f663): undefined reference to `led_classdev_unregister'
  drivers/built-in.o: In function `wbcir_remove':
  winbond-cir.c:(.devexit.text+0x7f23): undefined reference to `led_classdev_unregister'
  drivers/built-in.o: In function `fujitsu_cleanup':
  fujitsu-laptop.c:(.exit.text+0xbe37): undefined reference to `led_classdev_unregister'
  fujitsu-laptop.c:(.exit.text+0xbe53): undefined reference to `led_classdev_unregister'

It happens because the new INPUT_WINBOND_CIR driver relies
on new-leds infrastructure - but does not select it in
drivers/input/misc/Kconfig. But it selects LEDS_CLASS,
which confuses a number of other drivers into thinking
that all the leds infrastructure is in place.

Fix this by selecting NEW_LEDS as well, like similar drivers do.

Eventually, this whole leds infrastructure complexity should be
cleaned up, it's been going on for years.
