| |
Original reports and discussion: http://archives.andrew.net.au/lm-sensors/msg28512.html http://archives.andrew.net.au/lm-sensors/msg28581.html
Bottom line: The "bit" and "pcf" i2c algorithms should declare themselves fully I2C capable, but do not.
Credits go to Ian Campbell for noticing and proposing patches.
This is a backport from Linux 2.6.11-rc1.
