This patch introduces the use of devm_kzalloc and does away
with kfree in the probe function.

Some comments on this patch and driver:
- Here, after this change there will be a kfree on the failure of
the regmap_read too. I am not sure if driver is currently missing
it or there is something else happening here. Also, I think there
should be soc_device_unregister under the regmap_read.
- Moreover, get_maintainer.pl is not pointing me towards any particular
mailing list or maintainers. So, I am sending this patch to all
commiters as there are only three commits for this driver.
