* ARM: OMAP2+: Fix null pointer dereference and memory leak in ↵Kunwu Chan2023-11-301-0/+5
| | | | | | | | | | | | | | | | omap_soc_device_init kasprintf() returns a pointer to dynamically allocated memory which can be NULL upon failure. When 'soc_dev_attr->family' is NULL,it'll trigger the null pointer dereference issue, such as in 'soc_info_show'. And when 'soc_device_register' fails, it's necessary to release 'soc_dev_attr->family' to avoid memory leaks.

* ARM: OMAP2: Use custom soc attribute group instead of device_create_fileSudeep Holla2020-07-061-4/+8
| | | | | | | | | | | | | | | | | | | | | | | Commit c31e73121f4c ("base: soc: Handle custom soc information sysfs entries") introduced custom soc attribute group in soc_device_attribute structure but there are no users treewide. While trying to understand the motivation and tried to use it, it was found lot of existing custom attributes can moved to use it instead of device_create_file. Though most of these never remove/cleanup the custom attribute as they never call soc_device_unregister, using these custom attribute group eliminate the need for any cleanup as the driver infrastructure will take care of that. Let us remove device_create_file and start using the custom attribute group in soc_device_attribute.

Like last time, Renesas sh-mobile is now the platform with the most changes, followed by OMAP and EXYNOS. Two new platforms, TI Keystone and Rockchips RK3xxx are added in this branch, both containing almost no platform specific code at all, since they are using generic subsystem interfaces for clocks, pinctrl, interrupts etc. The device drivers are getting merged through the respective subsystem maintainer trees. One more SoC (u300) is now multiplatform capable and several others (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving towards that goal with this series but need more work. Also noteworthy is the work on PCI here, which is traditionally part of the SoC specific code. With the changes done by Thomas Petazzoni, we can now more easily have PCI host controller drivers as loadable modules and keep them separate from the platform code in drivers/pci/host. This has already led to the discovery that three platforms (exynos, spear and imx) are actually using an identical PCIe host controller and will be able to share a driver once support for spear and imx is added." * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (480 commits) ARM: integrator: let pciv3 use mem/premem from device tree ARM: integrator: set local side PCI addresses right ARM: dts: Add pcie controller node for exynos5440-ssdk5440 ARM: dts: Add pcie controller node for Samsung EXYNOS5440 SoC ARM: EXYNOS: Enable PCIe support for Exynos5440 pci: Add PCIe driver for Samsung Exynos ARM: OMAP5: voltagedomain data: remove temporary OMAP4 voltage data ARM: keystone: Move CPU bringup code to dedicated asm file ARM: multiplatform: always pick one CPU type ARM: imx: select syscon for IMX6SL ARM: keystone: select ARM_ERRATA_798181 only for SMP ARM: imx: Synertronixx scb9328 needs to select SOC_IMX1 ARM: OMAP2+: AM43x: resolve SMP related build error dmaengine: edma: enable build for AM33XX ARM: edma: Add EDMA crossbar event mux support ARM: edma: Add DT and runtime PM support to the private EDMA API dmaengine: edma: Add TI EDMA device tree binding arm: add basic support for Rockchip RK3066a boards arm: add debug uarts for rockchip rk29xx and rk3xxx series arm: Add basic clocks for Rockchip rk3066a SoCs ...

* ARM: OMAP2+: Remove bogus IS_ERR_OR_NULL checking from id.cTony Lindgren2013-05-091-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 6770b211 (ARM: OMAP2+: Export SoC information to userspace) had some broken return value handling as noted by Russell King: + soc_dev = soc_device_register(soc_dev_attr); + if (IS_ERR_OR_NULL(soc_dev)) { + kfree(soc_dev_attr); + return; + } + + parent = soc_device_to_device(soc_dev); + if (!IS_ERR_OR_NULL(parent)) + device_create_file(parent, &omap_soc_attr); This is nonsense. For the first, IS_ERR() is sufficient. For the second, tell me what error checking is required in the return value of this function: struct device *soc_device_to_device(struct soc_device *soc_dev) { return &soc_dev->dev; } when you've already determined that the passed soc_dev is a valid pointer. If you read the comments against the prototype: /** * soc_device_to_device - helper function to fetch struct device * @soc: Previously registered SoC device container */ struct device *soc_device_to_device(struct soc_device *soc); if "soc" is valid, it means the "previously registered SoC device container" must have succeeded and that can only happen if the struct device has been registered. Ergo, there will always be a valid struct device pointer for any registered SoC device container. Therefore, if soc_device_register() succeeds, then the return value from soc_device_to_device() will always be valid and no error checking of it is required. Simples. The rule as ever applies here: get to know the APIs your using and don't fumble around in the dark hoping that you'll get this stuff right. Fix it as noted by Russell.
