client->irq is already set correctly by of_i2c_register_devices - so I
don't think this sequence is necessary?
May be you are right. I will crosscheck.

Similarly, I wonder if pdata->io_serirq is just duplication of
client->irq and that should be set by the creator instead?
pdata->io_serirq stores the gpio number which will be converted into irq
number.
pdata->io_serirq is only use by static platform configuration not
devicetree configuration

missing:
MODULE_DEVICE_TABLE(of, of_st33zp24_i2c_match);
Oops. Good catch :).
+ #ifdef CONFIG_OF
+ .of_match_table = of_match_ptr(of_st33zp24_i2c_match),

The #ifdef is unnecessary, the of_match_ptr macro takes care of that
already.
Ok will clean that.
