Subject: [PATCH 5.10 119/717] media: platform: add missing put_device() call in mtk_jpeg_clk_init()

From: Yu Kuai <yukuai3@...wei.com>

[ Upstream commit f28a81a3b64270da3588174feff4628c36e0ff4e ]

if of_find_device_by_node() succeeds, mtk_jpeg_clk_init() doesn't have
a corresponding put_device(). Thus add put_device() to fix the exception
handling for this function implementation.
