Hi, Dongchun I think it need rebase on linuxtv/master. ________________________ BRs, Bingbu Cao From: Dongchun Zhu (朱东春) <Dongchun.Zhu@xxxxxxxxxxxx> Sent: Thursday, July 2, 2020 11:49 AM To: Sakari Ailus <sakari.ailus@xxxxxxxxxxxxxxx> Cc: linus.walleij@xxxxxxxxxx; bgolaszewski@xxxxxxxxxxxx; mchehab@xxxxxxxxxx; andriy.shevchenko@xxxxxxxxxxxxxxx; robh+dt@xxxxxxxxxx; drinkcat@xxxxxxxxxxxx; tfiga@xxxxxxxxxxxx; Erin Lo (羅雅齡) <erin.lo@xxxxxxxxxxxx>; Louis Kuo (郭德寧) <louis.kuo@xxxxxxxxxxxx>; Sj Huang (黃信璋) <sj.huang@xxxxxxxxxxxx>; matthias.bgg@xxxxxxxxx; Cao, Bingbu <bingbu.cao@xxxxxxxxx>; srv_heupstream <srv_heupstream@xxxxxxxxxxxx>; linux-mediatek@xxxxxxxxxxxxxxxxxxx; linux-arm-kernel@xxxxxxxxxxxxxxxxxxx; linux-media@xxxxxxxxxxxxxxx; devicetree@xxxxxxxxxxxxxxx; Shengnan Wang (王圣男) <shengnan.wang@xxxxxxxxxxxx> Subject: RE: [PATCH V9 0/2] media: i2c: Add support for DW9768 VCM 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 https://www.kernel.org/, on which I ran the git am <patch> command. The patch-applying process shows no error. -----------------8<------------------- [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 -----------------8<------------------- 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 parse-maintainers.pl script to check MAINTAINERS file before submitting patch. The result also reports no errors. -----------------8<------------------- [mtk15013@mtkslt307 linux]$perl scripts/parse-maintainers.pl [mtk15013@mtkslt307 linux]$ls -----------------8<------------------- As to Base64 encoding, I checked each patch file again. They are all encoded in UTF-8. As https://www.base64encode.org/ 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?

I mean trailing whitespaces. When applying the patch with git am, this is what you get: -----------------8<------------------- $ 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. $id: http://devicetree.org/schemas/media/i2c/dongwoon,dw9768.yaml# 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". -----------------8<------------------- Also the patches seem to be base64 encoded, something I haven't seen before. That is likely unrelated though. -- Regards, Sakari Ailus ************* MEDIATEK Confidentiality Notice ******************** The information contained in this e-mail message (including any attachments) may be confidential, proprietary, privileged, or otherwise exempt from disclosure under applicable laws.
