syscon regmap for disabled node?

[Suman Anna]

Hi Pankaj, Arnd, Lee,

I am testing some code to use a syscon/regmap interface and I find that
the syscon/regmap is initialized even on a disabled device node using a
"syscon" compatible property when I have expected it to fail. Prior to
commit bdb0066df96e ("mfd: syscon: Decouple syscon interface from
platform devices"), the driver would have never probed, and the
of_syscon_register() only checks for the compatible, but not if the
device node is available. Is this intentional or a bug?

regards
Suman
