511c06e3 - soc: Switch back to struct platform_driver::remove()

Tue, 29 Oct 2024 07:48:58 +0000

soc: Switch back to struct platform_driver::remove()After commit 0edb555a65d1 ("platform: Make platform_driver::remove()return void") .remove() is (again) the right callback to implement forplatform drivers.Convert all platform drivers below drivers/soc to use .remove(), withthe eventual goal to drop struct platform_driver::remove_new(). As.remove() and .remove_new() have the same prototypes, conversion is doneby just changing the structure member name in the driver initializer.On the way do a few whitespace changes to make indention consistent.Signed-off-by: Uwe Kleine-König Acked-by: Heiko Stuebner Acked-by: Herve Codina # for fsl/qe/{qmc,tsa}.cAcked-by: Bjorn Andersson # qcom partsAcked-by: Gabriel Somlo Acked-by: Andrew Jeffery # aspeedLink: https://lore.kernel.org/r/20241029074859.509587-2-u.kleine-koenig@baylibre.comSigned-off-by: Arnd Bergmann List of files: /linux-6.15/drivers/soc/mediatek/mtk-devapc.c

a129ac35 - soc/mediatek: mtk-devapc: Convert to platform remove callback returning void

Mon, 25 Sep 2023 09:55:05 +0000

soc/mediatek: mtk-devapc: Convert to platform remove callback returning voidThe .remove() callback for a platform driver returns an int which makesmany driver authors wrongly assume it's possible to do error handling byreturning an error code. However the value returned is ignored (apartfrom emitting a warning) and this typically results in resource leaks.To improve here there is a quest to make the remove callback returnvoid. In the first step of this quest all drivers are converted to.remove_new() which already returns void. Eventually after all driversare converted, .remove_new() will be renamed to .remove().Trivially convert this driver from always returning zero in the removecallback to the void returning variant.Reviewed-by: AngeloGioacchino Del Regno Link: https://lore.kernel.org/r/20230925095532.1984344-15-u.kleine-koenig@pengutronix.deSigned-off-by: Uwe Kleine-König List of files: /linux-6.15/drivers/soc/mediatek/mtk-devapc.c

d01e0aec - soc: mediatek: Explicitly include correct DT includes

Thu, 03 Aug 2023 22:42:59 +0000

soc: mediatek: Explicitly include correct DT includesThe DT of_device.h and of_platform.h date back to the separateof_platform_bus_type before it as merged into the regular platform bus.As part of that merge prepping Arm DT support 13 years ago, they"temporarily" include each other. They also include platform_device.hand of.h. As a result, there's a pretty much random mix of those includefiles used throughout the tree. In order to detangle these headers andreplace the implicit includes with struct declarations, users need toexplicitly include the correct includes.Reviewed-by: AngeloGioacchino Del Regno Signed-off-by: Rob Herring Link: https://lore.kernel.org/r/20230803-dt-header-cleanups-for-soc-v2-19-d8de2cc88bff@kernel.orgSigned-off-by: Arnd Bergmann List of files: /linux-6.15/drivers/soc/mediatek/mtk-devapc.c
