Commit 14621c7e5e72 ("ASoC: Consolidate CPU and CODEC DAI lookup") consolidated the lookup of CPU DAIs and CODEC DAIs into a single function. When matching a component by name for CODEC DAIs the code previous to the patch compared the name in the DAI link table with component->name. For CPU DAIs the code compared to dev_name(component->dev). The newly introduced function ended up using the later as well.
For most components dev_name(component->dev) and component->name are the same. The main notable exception are I2C devices where the driver name and the device name are concatenated to form the component name. By using dev_name(component->dev) instead of component->name the patch broke the matching of I2C CODECs by name.
This patch restores the original behavior by using component->name instead of dev_name(component->dev). This will be safe even for CPU DAIs since for CPU DAIs both are the same.
