Hi, Dongchun

Hi Sakari,

Sorry to bother you again, but I am so confused about the questions you raised.
I just synced mainline: 5.8-rc3 tarball from, on which I ran the git am <patch> command.
The patch-applying process shows no error.
[mtk15013@mtkslt307 linux]$git apply --check media-i2c-Add-support-for-DW9768-VCM.patch
[mtk15013@mtkslt307 linux]$git am media-i2c-Add-support-for-DW9768-VCM.patch
Applying: media: dt-bindings: media: i2c: Document DW9768 bindings
Applying: media: i2c: dw9768: Add DW9768 VCM driver

On the other hand, I also compared dongwoon,dw9768.yaml file with other media device dt-bindings(like imx219.yaml and ov8856.yaml).
It seems there are no apparent differences between them.
Especially, the sentence '# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause)' shall be common.
I dunno why here dongwoon,dw9768.yaml reports trailing whitespace warnings while ov8856.yaml is silent.

For the patch failed on MAINTAINERS, I am still curious what's wrong.
In fact, I locally have run script to check MAINTAINERS file before submitting patch.
The result also reports no errors.
[mtk15013@mtkslt307 linux]$perl scripts/
[mtk15013@mtkslt307 linux]$ls

As to Base64 encoding, I checked each patch file again. They are all encoded in UTF-8.
As says, for an example, '77' in ASCII format would be changed to 'T' in Based64-encoded format.
This means there shall be messy code if we adpoting Based64-encoded format.
But I cannot see garbled messages in the current patches.

The DW9768 serials-patch is attached.
@Tomasz @Andy @Rob could anyone help try to see whether the patch can be cherry-picked on Linux master branch or not?

Hi Dongchun,

I mean trailing whitespaces. When applying the patch with git am, this is what you get:

$ git am -s /tmp/patchset
Applying: media: dt-bindings: media: i2c: Document DW9768 bindings
.git/rebase-apply/patch:13: trailing whitespace.
# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause)
.git/rebase-apply/patch:14: trailing whitespace.
# Copyright (c) 2020 MediaTek Inc.
.git/rebase-apply/patch:15: trailing whitespace.
%YAML 1.2
.git/rebase-apply/patch:16: trailing whitespace.
.git/rebase-apply/patch:17: trailing whitespace.
error: patch failed: MAINTAINERS:5215
error: MAINTAINERS: patch does not apply Patch failed at 0001 media: dt-bindings: media: i2c: Document DW9768 bindings
hint: Use 'git am --show-current-patch' to see the failed patch When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".

Also the patches seem to be base64 encoded, something I haven't seen before. That is likely unrelated though.
