[PATCH 5.15 425/667] ASoC: sh: rz-ssi: Check return value of pm_runtime_resume_and_get()

[Greg Kroah-Hartman]

From: Heiner Kallweit <hkallweit1@xxxxxxxxx>

[ Upstream commit f04b4fb47d83b110a5b007fb2eddea862cfeb151 ]

The return value of pm_runtime_resume_and_get() needs to be checked to
avoid a usage count imbalance in the error case. This fix is basically
the same as 92c959bae2e5 ("reset: renesas: Fix Runtime PM usage"),
and the last step before pm_runtime_resume_and_get() can be annotated
as __must_check.
