2c19d015 - Input: switch back to struct platform_driver::remove()

Tue, 08 Oct 2024 09:00:10 +0000

Input: 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/input/ 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.While touching these files, make indention of the struct initializerconsistent in a few drivers.Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20241008090009.462836-2-u.kleine-koenig@baylibre.comSigned-off-by: Dmitry Torokhov List of files: /linux-6.15/drivers/input/touchscreen/sun4i-ts.c

1b1904f6 - Input: sun4i-ts - convert to platform remove callback returning void

Wed, 20 Sep 2023 12:58:26 +0000

Input: sun4i-ts - 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.Signed-off-by: Uwe Kleine-König Acked-by: Jernej Skrabec Link: https://lore.kernel.org/r/20230920125829.1478827-50-u.kleine-koenig@pengutronix.deSigned-off-by: Dmitry Torokhov List of files: /linux-6.15/drivers/input/touchscreen/sun4i-ts.c

17e8351a - thermal: consistently use int for temperatures

Fri, 24 Jul 2015 06:12:54 +0000

thermal: consistently use int for temperaturesThe thermal code uses int, long and unsigned long for temperaturesin different places.Using an unsigned type limits the thermal framework to positivetemperatures without need. Also several drivers currently will reporttemperatures near UINT_MAX for temperatures below 0°C. This will probablyimmediately shut the machine down due to overtemperature if started below0°C.'long' is 64bit on several architectures. This is not needed since INT_MAX °mCis above the melting point of all known materials.Consistently use a plain 'int' for temperatures throughout the thermal code andthe drivers. This only changes the places in the drivers where the temperatureis passed around as pointer, when drivers internally use another type this isnot changed.Signed-off-by: Sascha Hauer Acked-by: Geert Uytterhoeven Reviewed-by: Jean Delvare Reviewed-by: Lukasz Majewski Reviewed-by: Darren Hart Reviewed-by: Heiko Stuebner Reviewed-by: Peter Feuerer Cc: Punit Agrawal Cc: Zhang Rui Cc: Eduardo Valentin Cc: linux-pm@vger.kernel.orgCc: linux-kernel@vger.kernel.orgCc: Jean Delvare Cc: Peter Feuerer Cc: Heiko Stuebner Cc: Lukasz Majewski Cc: Stephen Warren Cc: Thierry Reding Cc: linux-acpi@vger.kernel.orgCc: platform-driver-x86@vger.kernel.orgCc: linux-arm-kernel@lists.infradead.orgCc: linux-omap@vger.kernel.orgCc: linux-samsung-soc@vger.kernel.orgCc: Guenter Roeck Cc: Rafael J.
