Subject: [PATCH v3] ASoC: Replace snd_soc_acpi_check_hid with acpi_dev_present
Date: Fri, 10 Nov 2017 18:36:17 +0000	[thread overview]
Message-ID: <0100015fa737dec2-4d7283d5-bba0-4270-9f92-8f258d2835dd-000000@email.amazonses.com> (raw)

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.

Signed-off-by: Jeremy Cline <jeremy@jcline.org>

Changes in v3:
  - Remove the unnecessary "== true" and "!= true"
