Subject: [PATCH] ASoC: fix unmet dependencies on GPIOLIB for SND_SOC_RT1015P
Date:   Thu, 28 Oct 2021 20:12:25 -0400

When SND_SOC_MT8192_MT6359_RT1015_RT5682,
SND_SOC_MT8192_MT6359_RT1015_RT5682,
SND_SOC_MT8183_DA7219_MAX98357A, or
SND_SOC_MT8183_MT6358_TS3A227E_MAX98357A is selected,
and GPIOLIB is not selected, Kbuild gives the following
warnings, respectively:

WARNING: unmet direct dependencies detected for SND_SOC_DMIC

WARNING: unmet direct dependencies detected for SND_SOC_RT1015P

This is because these config options select SND_SOC_RT1015P
without selecting or depending on GPIOLIB, despite
SND_SOC_RT1015P depending on GPIOLIB.

These unmet dependency bugs were detected by Kismet,
a static analysis tool for Kconfig. Please advise if this
is not the appropriate solution.
