As Kay Sievers explained that i2c adapters should be bus devices rather than class devices, convert them. [PATCH 1/4] Add support for compatibility classes [PATCH 2/4] i2c: Convert i2c clients to a device type [PATCH 3/4] i2c: Convert i2c adapters to bus devices [PATCH 4/4] i2c: Provide compatibility links for i2c adapters drivers/base/class.c | 87 +++++++++++++++++++++++++ drivers/i2c/Kconfig | 8 ++ drivers/i2c/i2c-core.c | 165 +++++++++++++++++++++++++++++++++---------------- include/linux/device.h | 8 ++ 4 files changed, 217 insertions(+), 51 deletions(-) Care has been taken to not break user-space compatibility. I have also updated libsensors and sensors-detect already to look for i2c adapters in /sys/bus/i2c/devices rather than /sys/class/i2c-adapter. I am not aware of other user-space applications or libraries using /sys/class/i2c-adapter, but if you do please tell me. Improvements are possible on the power management side, but I did not have the time to deal with this now, so this is left for later. -- Jean Delvare -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
