Summary

0000022: Backporting lm93 sensor driver fails due to missing i2c_smbus_read_block_data() function

Description

Attempting to backport the lm93 hwmon sensor driver fails due to missing i2c_smbus_read_block_data() function in i2c-core.

Additional Information

The function i2c_smbus_read_block_data() function was removed and only later restored around kernel-2.6.22 in i2c-core.

See here for details:

http://lists.lm-sensors.org/pipermail/lm-sensors/2007-April/019430.html [^]

Without updating i2c-core it will not be possible to easily backport lm93 to RHEL5.3
