Subject: [PATCH v5 0/8] Add support for best effort block read emulation

This is version 5 for adding i2c_smbus_read_i2c_block_data_or_emulated
to i2c-core.

Jonathan, I did not add your Reviewed-by to the patch adding the 
i2c_smbus_read_i2c_block_data_or_emulated function since I made some
changes to the code.

Thanks,
Irina

Changes from v4:
 - optimized the code for i2c_smbus_read_i2c_block_data_or_emulated as
Wolfram suggested
 - dropped the error message from i2c_smbus_read_i2c_block_data_or_emulated
 - fixed documentation to specify I2C_SMBUS_BLOCK_MAX instead of 32

Changes from v3:
 - when reading an odd number of bytes using word emulation, read an even
number of bytes using word reads and the last byte using byte read
 - code styling changes to improve readability
 - add a comment about addressing assumptions to the
i2c_smbus_read_i2c_block_data_or_emulated function as Jonathan suggested
 - add Acked-by from Jonathan and Srinivas to the iio changes

Changes from v2:
 - changed bmc150-accel, kxcjk-1013 and bmg160 drivers to use
i2c_smbus_read_i2c_block_data_or_emulated

Changes from v1:
 - dropped the RFC tag
 - changed at24 to use i2c_smbus_read_i2c_block_data_or_emulated
 - when reading an odd number of bytes using word emulation, read an even
number of bytes and drop the last one
 - add a comment that this might not be suitable for all I2C slaves
