[PATCH v2 1/2] of: add optional options parameter to of_find_node_by_path()

From: Leif Lindholm

Previous message: Leif Lindholm: "[PATCH v2 0/2] of: support passing console options with stdout-path"
In reply to: Leif Lindholm: "[PATCH v2 0/2] of: support passing console options with stdout-path"
Next in thread: Grant Likely: "Re: [PATCH v2 1/2] of: add optional options parameter to of_find_node_by_path()"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Update of_find_node_by_path():
1) Ignore any part of the path beyond and including the ':' separator.
2) Set the new provided pointer argument to the beginning of the string
following the ':' separator.

Coccinelle fixup using:

@@
expression E1;
@@

- of_find_node_by_path(E1)
+ of_find_node_by_path(E1, NULL)

drivers/of/resolver.c manually updated, since spatch fails to parse
it correctly.
