ASoC: codec: sma1307: Remove including of_gpio.h
of_gpio.h is deprecated. And there is no user in this driver
using API in of_gpio.h, so remove it.

ASoC: sma1307: Fix error handling in sma1307_setting_loaded()
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.

ASoC: sma1307: Add NULL check in sma1307_setting_loaded()
All varibale allocated by kzalloc and devm_kzalloc could be NULL.
Multiple pointer checks and their cleanup are added.

This issue is found by our static analysis tool

ASoC: sma1307: Use SOC_SINGLE_EXT() helper macro
Rather than open coding use the helper macro provided by the ASoC core.

ASoC: Drop explicit initialization of struct i2c_device_id::driver_data to 0
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.

ASoC: sma1307: fix uninitialized variable refence
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.

ASoC: sma1307: Fix invalid logical judgement
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.
