cdx: don't select CONFIG_GENERIC_MSI_IRQ

2025-10-15T10:03:47Z

[ Upstream commit ab1d8dda32e9507ca3bfb6b43661aeaa27f7bd82 ] x86 does not use CONFIG_GENERIC_MSI_IRQ, and trying to enable it anyway results in a build failure: In file included from include/linux/ssb/ssb.h:10, from drivers/ssb/pcihost_wrapper.c:18: include/linux/gpio/driver.h:41:33: error: field 'msiinfo' has incomplete type 41 | msi_alloc_info_t msiinfo; | ^~~~~~~ In file included from include/linux/kvm_host.h:19, from arch/x86/events/intel/core.c:17: include/linux/msi.h:528:33: error: field 'alloc_info' has incomplete type 528 | msi_alloc_info_t alloc_info; Change the driver to actually build without this symbol and remove the incorrect 'select' statements.

cdx: Fix off-by-one error in cdx_rpmsg_probe()

2025-08-19T10:55:16Z

In cdx_rpmsg_probe(), strscpy() is incorrectly called with the length of the source string (excluding the NUL terminator) rather than the size of the destination buffer. This results in one character less being copied from 'cdx_rpmsg_id_table[0].name' to 'chinfo.name'. Use the destination buffer size instead to ensure the name is copied correctly.

cdx: Fix missing GENERIC_MSI_IRQ on compile test

2025-07-16T12:17:31Z

CDX_BUS driver uses msi_setup_device_data() which is selected by GENERIC_MSI_IRQ, thus compile testing without the latter failed: /usr/bin/ld: drivers/cdx/cdx.o: in function `cdx_probe': build/drivers/cdx/cdx.c:314: undefined reference to `msi_setup_device_data' Reported-by: Randy Dunlap Closes: https://lore.kernel.org/all/b2c54a12-480c-448a-8b90-333cb03d9c14@infradead.org/ Fixes: 7f81907b7e3f ("cdx: Enable compile testing") Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20250716064903.52397-2-krzysztof.kozlowski@linaro.org Signed-off-by: Greg Kroah-Hartman

Struct driver in platform_driver is zero-ed so there is no need to assign its 'pm' member to NULL. Signed-off-by: Krzysztof Kozlowski Acked-by: Nikhil Agarwal Link: https://lore.kernel.org/r/20250502-cdx-clean-v3-5-6aaa5b369fc5@linaro.org Signed-off-by: Greg Kroah-Hartman

cdx: controller: Drop useless probe success message

2025-07-01T10:18:07Z

Drivers should be silent on probe success, unless they print some useful information. Printing "hey I probed" is not useful and kernel already gives mechanism to investigate that (e.g. sysfs, tracing, initcall debug).

cdx: Enable compile testing

2025-07-01T10:18:07Z

There is no code limited to ARM64 or OF/Devicetree in the CDX bus driver, so CDX_BUS can be compile tested on all platforms. CDX_CONTROLLER on the other hand selects REMOTEPROC which depends on HAS_DMA, so add that dependency for compile testing.

irqdomain: cdx: Switch to of_fwnode_handle()

2025-04-25T13:53:38Z

of_node_to_fwnode() is irqdomain's reimplementation of the "officially" defined of_fwnode_handle(). The former is in the process of being removed, so use the latter instead.
