The SBS battery implements SMBus block reads. Currently the driver "emulates" this by doing an I2C byte read for the length followed by an I2C block read. The I2C subsystem actually provides a proper API for doing SMBus block reads, which can and should be used instead. The current implementation does not properly handle packet error checking (PEC). Not all upstream systems using sbs-battery have I2C bus drivers supporting I2C_M_RECV_LEN, so old implementation is kept as fallback to keep things working. But this prints a warning, which hopefully results in people implementing support for it.
