The change is fine, but the reference to commit 'd25ea659' is not for
two reasons:
- when you rebase the tree, you will get a different ID
- the recommended format for referring to another commit is to list it with
12 digits and the one-line summary like this:
commit d25ea659bc37 ("asm-generic/io.h: move
ioremap_nocache/ioremap_uc/ioremap_wc/ioremap_…")
- Ideally you use a 'Fixes:' tag in the patch description.
You can add these lines in your .gitconfig to help you here
[alias]
fixes = show --format='Fixes: %h (\"%s\")' -s
[core]
abbrev = 12
That will give you a 'git fixes' command to output the Fixes: line
in the correct format for future bug fixes. For this particular change,
I would actually just merge the two patches into one patch that
then doesn't break anything in the first place.
