I think it woud be good if you provided a helper macro for setting one
of the indicators rather than open coding the _NONE constant. e.g.
#define set_power_indicator(ctrl, x) pciehp_set_indicators(ctrl, (x),
PCI_EXP_SLTCTL_ATTN_IND_NONE);
then you can do:
set_power_indicator(ctrl, PCI_EXP_SLTCTL_PWR_IND_BLINK);
which is a bit nicer to read.
