[PATCH v2 6/7] ASoC: tlv320*: use i2c_match_id and simple i2c probe

Stephen Kitt
2022-04-15T16:07:22Z

In the context of an i2c probe, i2c_match_id with the module id table
and the probed client never returns null, so removing the null check
on the i2c_device_id pointer is safe.

The i2c id tables are moved up before the probe function, as
suggested by Wolfram Sang, except where the existing code already had
a declaration for the of_device_id table.
