Thus delete an extra initialisation. Hi, Just a small nit on the patch title: "delete owner assignment" is virtually useless as a title because it has no meaning without the broader context and only describes the literal change. It's like naming a patch "add a line" or "change the code"; it serves no purpose. How about "backlight-tosa: delete _unnecessary_ assignment"? This immediately communicates the reason for/intent of the patch (there is unnecessary code, thus we can simplify it). (Sorry about singling out this patch and the apparent bikeshedding, this comment obviously applies to a lot of patches by a lot of authors!) Thanks, Vegard ``` ## Re: backlight-tosa: Delete owner assignment - From: SF Markus Elfring \ - Date: 2016-08-15 13:25:54 - Message: https://ratatoskr.run/linux-fbdev/2016/08/4814613.md ```text >> The field "owner" is set by core.

Do you want that I add any more background information to the commit message? > How about "backlight-tosa: delete _unnecessary_ assignment"? Will the underlined key word trigger any related software development concerns? Would another look be needed on how the usage of the mentioned data structure element was reduced over time?

No, the rest of the commit message is fine. I was only concerned about the patch title (the first line) since that's what appears frequently in patch lists (cgit, shortlogs, email/archives), etc. >> How about "backlight-tosa: delete _unnecessary_ assignment"? > > Will the underlined key word trigger any related software > development concerns? No, the emphasis was just for the email, I wouldn't put that in the actual commit log. > Would another look be needed on how the usage of the mentioned data > structure element was reduced over time? No, it's fine, it's really just about the patch title :-) Thanks, Vegard ``` ## Re: \[PATCH\] backlight-tosa: Delete owner assignment - From: Lee Jones \ - Date: 2016-08-15 13:44:44 - Message: https://ratatoskr.run/linux-fbdev/2016/08/4814631.md ```text On Mon, 15 Aug 2016, Vegard Nossum wrote: > On 15 August 2016 at 13:12, SF Markus Elfring > [ref] wrote: > > From: Markus Elfring > > Date: Mon, 15 Aug 2016 13:03:29 +0200 > > > > The field "owner" is set by core.
