Jean Delvare 6be99c5182 i2c: i801: Fix block process call transactions ... [ Upstream commit c1c9d0f6f7 ] According to the Intel datasheets, software must reset the block buffer index twice for block process call transactions: once before writing the outgoing data to the buffer, and once again before reading the incoming data from the buffer. The driver is currently missing the second reset, causing the wrong portion of the block buffer to be read.
