    i2c: Shrink struct i2c_client · 2096b956
    David Brownell authored
    This shrinks the size of "struct i2c_client" by 40 bytes:
    
     - Substantially shrinks the string used to identify the chip type
     - The "flags" don't need to be so big
     - Removes some internal padding
    
    It also adds kerneldoc for that struct, explaining how "name" is really a
    chip type identifier; it's otherwise potentially confusing.
    
    Because the I2C_NAME_SIZE symbol was abused for both i2c_client.name
    and for i2c_adapter.name, this needed to affect i2c_adapter too.  The
    adapters which used that symbol now use the more-obviously-correct
    idiom of taking the size of that field.
    
    JD: Shorten i2c_adapter.name from 50 to 48 bytes while we're here, to
    avoid wasting space in padding.
