ASoC: codecs: nau8325: Silence uninitialized variables warnings

2025-12-18T13:00:17Z

commit 2c7e5e17c05f1d5e10e63e1baff2b362cd08dcd6 upstream. clang W=1 builds warn: nau8325.c:430:13: error: variable 'n2_max' is uninitialized when used here [-Werror,-Wuninitialized] which are false positive, because the variables will be always initialized when used (guarded by mclk_max!=0 check). However initializing them upfront makes the code more obvious and easier, plus it silences the warning.

ASoC: nau8325: use simple i2c probe function

2025-12-18T12:59:58Z

[ Upstream commit b4d072c98e47c562834f2a050ca98a1c709ef4f9 ] The i2c probe functions here don't use the id information provided in their second argument, so the single-parameter i2c probe function ("probe_new") can be used instead. This avoids scanning the identifier tables during probes.

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

2024-05-03T02:08:06Z

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.
