[PATCH v2 2/4] staging: media: intel-ipu3: reduce length of line

[Mitali Borkar]

Reduced length of line as it was exceeding 100 characters by removing
comments from same line and adding it to previous line. This makes code
neater, and meets linux kernel coding style.

Do you still have the other two patches in your tree? This doesn't apply
here due to the different attribute syntax.

Could you drop them and then submit v3?

I am extremely sorry Sir, but I am still learning to use git, drop them
means to delete those commits? Even if I delete those, this patch was
made after those, so the changes I made then will remain as it is, so
what to do now?

No worries.

Yes, please remove the two commits, as you need to use the same (or at
least non-conflicting) baseline for the patches compared to the tree where
the patches will be applied.

So in practice what you need to do is to rebase these four patches on
linux-media tree's master branch and resolve the resulting conflict in this
patch (as the preceding patches no longer have the attribute changes).

The -i option for git rebase in particular is useful.
