[ Upstream commit 27c3943683f74e35e1d390ceb2e3639eff616ad6 ]
mtk_vcodec_release_dec_pm() will be called in two places:
a. mtk_vcodec_init_dec_pm() succeed while mtk_vcodec_probe() return error.
b. mtk_vcodec_dec_remove().
In both cases put_device() call is needed, since of_find_device_by_node()
was called in mtk_vcodec_init_dec_pm() previously.
Thus add put_devices() call in mtk_vcodec_release_dec_pm()

Fix this bug:
drivers/media/platform/mtk-vcodec/vdec_drv_if.c:38 vdec_if_init() info: ignoring unreachable code.
With is indeed a real problem that prevents the driver to work!
While here, also remove an used var, as reported by smatch:
drivers/media/platform/mtk-vcodec/mtk_vcodec_dec_pm.c: In function 'mtk_vcodec_init_dec_pm':
drivers/media/platform/mtk-vcodec/mtk_vcodec_dec_pm.c:29:17: warning: variable 'dev' set but not used [-Wunused-but-set-variable]
struct device *dev;
