Currently, there are two entries for CONFIG_GOLDFISH. In arch/x86/Kconfig: config GOLDFISH def_bool y depends on X86_GOLDFISH In drivers/platform/goldfish/Kconfig: menuconfig GOLDFISH bool "Platform support for Goldfish virtual devices" depends on HAS_IOMEM && HAS_DMA While Kconfig allows multiple entries, it generally leads to tricky code. Prior to commit bd2f348d ("goldfish: refactor goldfish platform configs"), CONFIG_GOLDFISH was an alias of CONFIG_X86_GOLDFISH. After the mentioned commit added the second entry with a user prompt, the former provides the 'default' property that is effective only when X86_GOLDFISH=y. Merge them tegether to clarify how it has worked in the past 8 years.

The C standard specifies that there is no need to cast from a pointer to void [1]. Therefore, it can be safely dropped. [1] C Standard Committee: https://c0x.shape-of-code.com/6.3.2.3.htmlSigned-off-by:

The functions below are only used within the context of drivers/greybus/core.c, so move them all into core and drop their 'inline' specifiers: is_gb_host_device(), is_gb_module(), is_gb_interface(), is_gb_control(), is_gb_bundle() and is_gb_svc(). Suggested-by:

ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). Note that the upper limit of ida_simple_get() is exclusive, but the one of ida_alloc_range()/ida_alloc_max() is inclusive. So a -1 has been added when needed. Signed-off-by:

The MT8183 has not one but two efuse devices. The static name and ID causes the second efuse device to fail to probe, due to duplicate sysfs entries. With the rework of the mtk-socinfo driver, lookup by name is no longer necessary. The custom name can simply be dropped. Signed-off-by:

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. Signed-off-by:
