PCI: pciehp: Remove pciehp_green_led_{on,off,blink}()
Remove pciehp_green_led_{on,off,blink}() and use pciehp_set_indicators() instead, since the code is mostly the same. [bhelgaas: drop set_power_indicator() wrapper to reduce the number of interfaces] Link: https://lore.kernel.org/r/20190903111021.1559-5-efremov@linux.com Signed-off-by: Denis Efremov <efremov@linux.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com>
