[PATCH RESEND v6 0/2] Fixing check patch styling issues

[PATCH RESEND v6 0/2] Fixing check patch styling issues

[Raghu Halharvi]

v6 changes:
- PATCH RESEND, the v5 was approved was not committed, Ira suggested to
  resend both patches.

v5 changes:
- Updated the missing reviewed tag in "cxl/mbox: Remove redundant
  dev_err() after failed mem alloc" patch (Dave Jiang)

v4 changes:
- Updated the respective patches with reviewers tags for respective
  patches(Dave Jiang)

v3 changes:
- Update the cover letter and commit message with full author
  name(Fabio/Alison)
- Correct the "typo error" in commit message(Fabio)

v2 changes:
Thanks Alison, Ira for your comments, modified the v1 patches as
suggested.
Dropped the patch containing tab changes in port.c

v1 cover letter:
The following patches are cleanup or fixing the styling issues found
using checkpatch

In cxl/core/mbox.c, in case of null check failure, returning errno or
-ENOMEM in this case is good enough, removing the redundant dev_err
message.

In cxl/core/region.c, the else is not required after the return
statement, cleaned it up.

Verified the build and sanity by booting the guest VM using the freshly
built components.

[PATCH RESEND v6 1/2] cxl/mbox: Remove redundant dev_err() after failed mem alloc

[Raghu Halharvi]

Issue found with checkpatch

A return of errno should be good enough if the memory allocation fails,
the error message here is redundant as per the coding style, removing
it.

Hi Raghu,

If this was a true RESEND, the version number should not have changed.
See: Documentation/process/submitting-patches.rst

Alas, this v6 has changes from v5 that are not listed here, so this
is not a RESEND, it is a new version.

Both patches were rebased, and in Patch 1 that led to a changed
function name too.

What to do? 
How about you send a reply to this cover letter with the v5->v6
changelog, and let's see if that's clear enough.

Thanks,
Alison
