[PATCH v2 1/2] of: add optional options parameter to of_find_node_by_path()
Leif Lindholm
leif.lindholm at linaro.org
Wed Nov 26 09:40:39 PST 2014
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.
