We have to read 512 bytes only, therefore read performance isn't really a concern. Don't bother the user if i2c block read isn't supported. For i2c_smbus_read_i2c_block_data_or_emulated() to work it's sufficient if I2C_FUNC_SMBUS_READ_I2C_BLOCK or I2C_FUNC_SMBUS_READ_BYTE_DATA is supported. Therefore remove the check for I2C_FUNC_SMBUS_READ_WORD_DATA. In addition check for I2C_FUNC_SMBUS_WRITE_BYTE (included in I2C_FUNC_SMBUS_BYTE) which is needed for setting the page.

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.
