Subject: [PATCH 1/7] media: platform: add missing put_device() call in mtk_jpeg_clk_init()

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

Fixes: 648372a87cee ("media: platform: Change the call functions of getting/enable/disable the jpeg's clock")
