CONFIG_PM covers runtime only PM.quoted
I am a bit confused by this description. CONFIG_PM_RUNTIME covers runtime PM, no?The issue is that CONFIG_PM doesn't actually enable any of the PM callbacks, it only allows you to enable CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME. This means that if you use CONFIG_PM to protect your system sleep callbacks they may end up unreferenced if only runtime PM is enabled.
Thanks for the explanation! Laxman, could you update the description to reflect that? -- Pengutronix e.K. | Wolfram Sang | Industrial Linux Solutions | http://www.pengutronix.de/ |
