Subject: ipmi: Fix the I2C address extraction from SPMI tables
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=70f95b76f155153a2a51a9a4568b9bcd4e573f5c;p=deliverable%2Flinux.git

ipmi: Fix the I2C address extraction from SPMI tables

Unlike everywhere else in the IPMI specification, the I2C address
specified in the SPMI table is not shifted to the left one bit with
the LSB zero.  Instead it is not shifted with the MSB zero.
