Hello!
This patch series cleans up some checkpatch fixes in erofs. The patches
include balancing conditional braces and fixing some indentation. No testing
done, all patches build and checkpath cleanly.
Caitlyn (2):
staging/erofs/xattr.h: Fixed misaligned function arguments.
staging/erofs: Balanced braces around a few conditional statements.

The only valid place is here.

I think you need to work on the latest staging tree or linux-next.
This patchset cannot be applied (there is the only valid place in inode.c,
I will reply in the following patch.)

There is actually balanced braces in linux-next.

There is not the "goto repeat" in linux-next anymore.

Which tree did these changes go in through please Gao? I believe
Caitlyn was working off of the staging-next branch of Greg's staging
tree.
thanks,
Tobin.

I don't think so, the reason is that unzip_vle.c was renamed to zdata.c
months ago, see:
https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git/tree/drivers/staging/erofs?h=staging-next
so I think the patch is outdated when I first look at it.

Gao,
I see now that I was on an outdated revision (Linux 5.3-rc4) of the
staging-next branch of Greg's staging tree, from
before that change was merged. I'll be certain that I'm fully
up-to-date before submitting future patches.
Thanks all for your time and assistance, and Gao and Joe for the
review comments as well, I'll review and submit
an appropriate patch series at a later time.
Thanks,
Caitlyn Finn
