[PATCH 5.4 187/314] ASoC: fix incomplete error-handling in img_i2s_in_probe.

[Greg Kroah-Hartman]

From: Qiushi Wu <wu000...@umn.edu>

[ Upstream commit 25bf943e4e7b47282bd86ae7d39e039217ebb007 ]

Function "pm_runtime_get_sync()" is not handled by "pm_runtime_put()"
if "PTR_ERR(rst) == -EPROBE_DEFER". Fix this issue by adding
"pm_runtime_put()" into this error path.

Fixes: f65bb92ca12e ("ASoC: img-i2s-in: Add runtime PM")
