Hi all, After merging the spi tree, today's linux-next build (htmldocs) produced this warning: Warning: /sys/devices/pci0000:00//fw_version is defined 2 times: Documentation/ABI/testing/sysfs-bus-pci-devices-avs:0 Documentation/ABI/testing/sysfs-bus-pci-devices-catpt:0 Introduced by commit 148b93a5062d ("ASoC: Intel: avs: Expose FW version with sysfs") You need to make the "" part unique. -- Cheers, Stephen Rothwell
