[Nouveau] [PATCH 33/53] drm/nouveau: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

[Nouveau] [PATCH 00/53] drm: Convert to platform remove callback returning void
Hello,
this patch series adapts the platform drivers below drivers/gpu/drm
to use the .remove_new() callback. Compared to the traditional .remove()
callback .remove_new() returns no value. This is a good thing because
the driver core doesn't (and cannot) cope for errors during remove. The
only effect of a non-zero return value in .remove() is that the driver
core emits a warning. The device is removed anyhow and an early return
from .remove() usually yields a resource leak.
By changing the remove callback to return void driver authors cannot
reasonably (but wrongly) assume any more that there happens some kind of
cleanup later.
Best regards
Uwe

[Nouveau] [PATCH 00/53] drm: Convert to platform remove callback returning void
Hi, 2023? 5? 8? (?) ?? 1:32, Uwe Kleine-K?nig <u.kleine-koenig at pengutronix.de>?? ??:> > Hello, > > this patch series adapts the platform drivers below drivers/gpu/drm > to use the .remove_new() callback. Compared to the traditional .remove() > callback .remove_new() returns no value. This is a good thing becauseFirst of all, I apologize for the delay in providing my review comments. Not related to this patch but seems that the "remove_new" callback naming implicitly implies that there is no need to return anything since its return type is void. To help users understand the intended behavior based on the callback name, how about considering a modified naming convention like "remove_no_return" or something similar? The relevant patch has already been merged as outlined below, author Uwe Kleine-K?nig <u.kleine-koenig at pengutronix.de> 2022-12-09 16:09:14 +0100 committer Greg Kroah-Hartman <gregkh at linuxfoundation.org> 2023-01-17 19:04:17 +0100 commit 5c5a7680e67ba6fbbb5f4d79fa41485450c1985c (patch) tree 0b6dbc003a6bb4a3f7fb084d31326bbfa3ba3f7c parent 7bbb89b420d9e290cb34864832de8fcdf2c140dc (diff) download linux-5c5a7680e67ba6fbbb5f4d79fa41485450c1985c.tar.gz platform: Provide a remove callback that returns no value Maybe a trivial thing but how about renaming it? I think the postfix, 'new', is a very generic word. I think you could introduce another patch for it if you think it's reasonable.
