Wow, my mistake, during rebase it seems I squashed three different
commits. Will fix this in next submission.

Thanks,

Looks like that's not the only change you're doing in this patch.

[U-Boot] [PATCH v6 27/31] mtd: move mtdparts_init() declaration

2018-08-16 Thread Miquel Raynal
mtdparts_init() is called from various source files. It is declared in
include/jffs2/load_kernel.h while it has nothing to do with jffs2
anymore.

Move its declaration to include/linux/mtd/partitions.h which has way
more meaning.
