[alsa-devel] [PATCH v2] ASoC: Replace snd_soc_acpi_check_hid with acpi_dev_present
Replace snd_soc_acpi_check_hid() with the generic acpi_dev_present() and remove the now unused snd_soc_acpi_check_hid function. This should have no functional change.

"== true" is redundant. Just use a style if (acpi_dev_present(...)) {
You don't need to follow the original code style.

Ditto, use if (!acpi_dev_present(...))
