Subject: [PATCH] treewide: fix incomplete error-handling in img_i2s_in_probe.
Date: Mon, 25 May 2020 00:50:11 -0500
Message-ID: <20200525055011.31925-1-wu000273@umn.edu> (raw)

From: Qiushi Wu <wu000273@umn.edu>

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")
Signed-off-by: Qiushi Wu <wu000273@umn.edu>
