fbdev: of: display_timing: fix refcount leak in of_get_display_timings()
[ Upstream commit eacf9840ae1285a1ef47eb0ce16d786e542bd4d7 ]
of_parse_phandle() returns a device_node with refcount incremented,
which is stored in 'entry' and then copied to 'native_mode'. When the
error paths at lines 184 or 192 jump to 'entryfail', native_mode's
refcount is not decremented, causing a refcount leak.
Fix this by changing the goto target from 'entryfail' to 'timingfail',
which properly calls of_node_put(native_mode) before cleanup.
Fixes: cc3f414cf2e4 ("video: add of helper for display timings/videomode")
