When you enable CONFIG_OF_LIVE, you will end up with a lot of conversions. To generate this commit, I used coccinelle excluding drivers/core/, include/dm/, and test/ The semantic patch that makes this change is as follows: <smpl> @@ expression dev; @@ -devfdt_get_addr(dev) +dev_read_addr(dev) </smpl> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
