This should be in a separate patch.

This is not a new structure, right? Where was this before? Surely it
should be removed from wherever it was in the same patch that places
it here?

Why are you changing the data type?

This is messy. Put them on separate lines.

First two what?

Put these on separate lines also please.

'alloc_size' should probably be 'buf_len'.

Please define the magic numbers.

Please define these magic numbers.

Why plus 2? Maybe define it.

As above.

I think this reads better (be sure to check the semantics):

ret = i2c_smbus_read_i2c_block_data(i2c, reg_addr, read_size, buf + 2);
if (ret < 0)
goto out;
if (ret != read_size) {
ret -EIO;
goto out;
}

memcpy(val, buf + 2, val_size);
if (crc_needed) {
crc = crc8(ddata->crc8_tbl, buf, val_size + 2, 0);
if (crc != buf[val_size + 2])
ret = -EIO;
}

out:
kfree(buf);
return 0;

Same comments as above.

No check for (ret == write_size)?

How about:

ret = i2c_smbus_write_i2c_block_data(i2c, reg_addr, write_size, buf + 2);
if (ret > 0)
ret = 0;

kfree(buf);
return ret;

Do you have to free the new devices you just allocated?

Why "__devm_*"? Isn't that an internal function?
