of_gpio.h is deprecated. And there is no user in this driver
using API in of_gpio.h, so remove it.

There are a couple bugs in this code:
1) The cleanup code calls kfree(sma1307->set.header) and
kfree(sma1307->set.def) but those functions were allocated using
devm_kzalloc(). It results in a double free. Delete all these
kfree() calls.
2) A missing call to kfree(data) if the checksum was wrong on this error
path:
if ((sma1307->set.checksum >> 8) != SMA1307_SETTING_CHECKSUM) {
Since the "data" pointer is supposed to be freed on every return, I
changed that to use the __free(kfree) cleanup attribute.

All varibale allocated by kzalloc and devm_kzalloc could be NULL.
Multiple pointer checks and their cleanup are added.

Rather than open coding use the helper macro provided by the ASoC core.

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

When firmware loading is disabled, gcc warns that the local
'fw' variable fails to get initialized:
sound/soc/codecs/sma1307.c: In function 'sma1307_setting_loaded.isra':
sound/soc/codecs/sma1307.c:1717:12: error: 'fw' is used uninitialized [-Werror=uninitialized]
1717 | if (!fw) {
| ^
sound/soc/codecs/sma1307.c:1712:32: note: 'fw' was declared here
1712 | const struct firmware *fw;
Check the return code from request_firmware() to ensure that the
firmware is correctly set, and drop the incorrect release_firmware()
on that uninitialized data.

In the function sma1307_dai_hw_params_amp, the variable
'ret' has not been assigned a value, so the logical judgement
is invalid, thus fix it.
