Subject: [PATCH] drm/msm/dsi: Fix missing put_device() call in dsi_get_phy
Date: Thu, 30 Dec 2021 07:09:40 +0000 [thread overview]
Message-ID: <20211230070943.18116-1-linmq006@gmail.com> (raw)
If of_find_device_by_node() succeeds, dsi_get_phy() doesn't
a corresponding put_device(). Thus add put_device() to fix the exception
handling.
Fixes: ec31abf ("drm/msm/dsi: Separate PHY to another platform device")
