When you enable CONFIG_OF_LIVE, you will end up with a lot of conversions. To help this tedious work, this commit converts devfdt_get_addr_ptr() to dev_read_addr_ptr() by coccinelle. I also removed redundant casts because dev_read_addr_ptr() returns an opaque pointer. To generate this commit, I ran the following semantic patch excluding include/dm/. <smpl> @@ type T; expression dev; @@ -(T *)devfdt_get_addr_ptr(dev) +dev_read_addr_ptr(dev) @@ expression dev; @@ -devfdt_get_addr_ptr(dev) +dev_read_addr_ptr(dev) </smpl> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org>
