[PATCH 4.9 079/245] wireless: carl9170: fix LEDS build errors & warnings

From: Greg Kroah-Hartman

[ Upstream commit 272fdc0c4542fad173b44965be02a16d6db95499 ]

kernel test robot reports over 200 build errors and warnings
that are due to this Kconfig problem when CARL9170=m,
MAC80211=y, and LEDS_CLASS=m.

WARNING: unmet direct dependencies detected for MAC80211_LEDS
Depends on [n]: NET [=y] && WIRELESS [=y] && MAC80211 [=y] && (LEDS_CLASS [=m]=y || LEDS_CLASS [=m]=MAC80211 [=y])
Selected by [m]:
- CARL9170_LEDS [=y] && NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_ATH [=y] && CARL9170 [=m]

CARL9170_LEDS selects MAC80211_LEDS even though its kconfig
dependencies are not met. This happens because 'select' does not follow
any Kconfig dependency chains.

Fix this by making CARL9170_LEDS depend on MAC80211_LEDS, where
the latter supplies any needed dependencies on LEDS_CLASS.

Say Y, unless you need the LEDs for firmware debugging.
