[PATCH] irqdomain: cdx: Switch to of_fwnode_handle()

[PATCH] irqdomain: cdx: Switch to of_fwnode_handle()

[Jiri Slaby (SUSE)]

of_node_to_fwnode() is irqdomain's reimplementation of the "officially"
defined of_fwnode_handle(). The former is in the process of being
removed, so use the latter instead.

This is an indepent patch, please apply directly.

The patch was previously a part of a large series [1], but I would like
maintainers to feed the independent parts through their trees.

This will go via Greg's char-misc tree.

@Greg: do you want me to resend, or will you dig it out with b4? It's:

I can dig it out.  but yes, the cdx stuff is a mess at times, it would
be nice if the maintainers there would get a better workflow :(

thanks,

As a MAINTAINER, I/Nikhil need to review. We do not maintain a tree and 
patches go via Greg's tree.

Yes, I understand, but how are patches supposed to reach him? If he 
maintains this in his tree, perhaps drivers/cdx/* deserves an entry in 
the MISC entry too?
