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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
