Heiner Kallweit a6b8bb6a81 i2c: i801: Fix handling SMBHSTCNT_PEC_EN ... Bit SMBHSTCNT_PEC_EN is used only if software calculates the CRC and uses register SMBPEC. This is not supported by the driver, it supports hw-calculation of CRC only (using bit SMBAUXSTS_CRCE). The chip spec states the following, therefore never set bit SMBHSTCNT_PEC_EN. Chapter SMBus CRC Generation and Checking If the AAC bit is set in the Auxiliary Control register, the PCH automatically calculates and drives CRC at the end of the transmitted packet for write cycles, and will check the CRC for read cycles. It will not transmit the contents of the PEC register for CRC. The PEC bit must not be set in the Host Control register. If this bit is set, unspecified behavior will result. This patch is based solely on the specification and compile-tested only, because I have no PEC-capable devices.
