According to the ast2600 datasheet and the linux aspeed i2c driver, the TXBUF transmission start position should be TXBUF[0] instead of TXBUF[1],so the arg pool_start is useless,and the address is not included in TXBUF.So even if Tx Count equals zero,there is at least 1 byte data needs to be transmitted,and M_TX_CMD should not be cleared at this condition.The driver url is: https://github.com/AspeedTech-BMC/linux/blob/aspeed-master-v5.15/drivers/i2c/busses/i2c-ast2600.c Signed-off-by: Hang Yu <francis_yuu@stu.pku.edu.cn> Fixes:6054fc73e8("aspeed/i2c: Add support for pool buffer transfers") Reviewed-by: Cédric Le Goater <clg@kaod.org> Signed-off-by: Cédric Le Goater <clg@kaod.org> (cherry picked from commit961faf3ddb) Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
