Make use of the same technique as for the version string, so that they are build only when they change. Signed-off-by: Simon Glass <sjg@chromium.org>

acpi: Create a new Kconfig for ACPI 2023-05-11T02:25:29+00:00 Simon Glass sjg@chromium.org 2023-05-04T22:54:57+00:00 0992a90daa80a17f9e7e33a56fd3f9660ee84c97 We have several Kconfig options for ACPI, but all relate to specific functions, such as generating tables and AML code. Add a new option which controls including basic ACPI library code, including the lib/acpi directory. This will allow us to add functions which are available even if table generation is not supported. Adjust the command to avoid a build error when ACPIGEN is not enabled. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

dm: treewide: Use uclass_first_device_err when accessing one device 2022-10-18T03:17:12+00:00 Michal Suchanek msuchanek@suse.de 2022-10-12T19:57:59+00:00 c726fc01cf669e3e2979da8665ef660e7d3ba464 There is a number of users that use uclass_first_device to access the first and (assumed) only device in uclass. Some check the return value of uclass_first_device and also that a device was returned which is exactly what uclass_first_device_err does. Some are not checking that a device was returned and can potentially crash if no device exists in the uclass. Finally there is one that returns NULL on error either way. Convert all of these to use uclass_first_device_err instead, the return value will be removed from uclass_first_device in a later patch.
