2024-10-11pinctrl: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/pinctrl to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

2023-10-13pinctrl: renesas: rzn1: Convert to platform remove callback returning voidUwe Kleine-König
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 ignored (apart from emitting a warning) 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. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "Mostly drivers! Nothing special: some new Qualcomm chips as usual, and the new NXP S32 and nVidia BlueField-3. Core changes: - Make a lot of pin controllers with GPIO and irqchips immutable, i.e. not living structs, but const structs. This is driving a changed initiated by the irqchip maintainers. New drivers: - New driver for the NXP S32 SoC pin controller - As part of a thorough cleanup and restructuring of the Ralink/Mediatek drivers, the Ralink MIPS pin control drivers were folded into the Mediatek directory and the family is renamed "mtmips". The Ralink chips live on as Mediatek MIPS family where new variants can be added. As part of this work also the device tree bindings were reworked. - New subdriver for the Qualcomm SM7150 SoC. - New subdriver for the Qualcomm IPQ9574 SoC. - New driver for the nVidia BlueField-3 SoC. - Support for the Qualcomm PMM8654AU mixed signal circuit GPIO. - Support for the Qualcomm PMI632 mixed signal circuit GPIO. Improvements: - Add some missing pins and generic cleanups on the Renesas r8a779g0 and r8a779g0 pin controllers. Generic Renesas extension for power source selection on several SoCs. - Misc cleanups for the Atmel AT91 and AT91-PIO4 pin controllers - Make the GPIO mode work on the Qualcomm SM8550-lpass-lpi driver. - Several device tree binding cleanups as the binding YAML syntax is solidifying" * tag 'pinctrl-v6.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (153 commits) pinctrl-bcm2835.c: fix race condition when setting gpio dir dt-bindings: pinctrl: qcom,sm8150: Drop duplicate function value "atest_usb2" dt-bindings: pinctrl: qcom: Add few missing functions pinctrl: qcom: spmi-gpio: Add PMI632 support dt-bindings: pinctrl: qcom,pmic-gpio: add PMI632 pinctrl: wpcm450: select MFD_SYSCON pinctrl: qcom ssbi-gpio: Convert to immutable irq_chip pinctrl: qcom ssbi-mpp: Convert to immutable irq_chip pinctrl: qcom spmi-mpp: Convert to immutable irq_chip pinctrl: plgpio: Convert to immutable irq_chip pinctrl: pistachio: Convert to immutable irq_chip pinctrl: pic32: Convert to immutable irq_chip pinctrl: sx150x: Convert to immutable irq_chip pinctrl: stmfx: Convert to immutable irq_chip pinctrl: st: Convert to immutable irq_chip pinctrl: mcp23s08: Convert to immutable irq_chip pinctrl: equilibrium: Convert to immutable irq_chip pinctrl: npcm7xx: Convert to immutable irq_chip pinctrl: armada-37xx: Convert to immutable irq_chip pinctrl: nsp: Convert to immutable irq_chip ...
2023-04-13pinctrl: renesas: remove MODULE_LICENSE in non-modulesNick Alcock
Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res' after devm_ioremap_resource() that will check it to avoid null-ptr-deref.

2020-09-15pinctrl: Rename sh-pfc to renesasGeert Uytterhoeven
The drivers/pinctrl/sh-pfc subdirectory was originally created to group pin control drivers for various Renesas SuperH and SH-Mobile platforms. However, the name "sh-pfc" no longer reflects its contents, as the directory now contains pin control drivers for Renesas SuperH, ARM32, and ARM64 SoCs. Hence rename the subdirectory from drivers/pinctrl/sh-pfc to drivers/pinctrl/renesas, and the related Kconfig symbol from PINCTRL_SH_PFC to PINCTRL_RENESAS. Rename the git branch in MAINTAINERS, too, for consistency. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Link: https://lore.kernel.org/r/20200909131534.12897-3-geert+renesas@glider.be
