2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada1-1/+1
The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: <smpl> @@ typedef bd_t; @@ -bd_t +struct bd_info </smpl> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
