drm/panel: type promotion bug in s6e8aa0_read_mtp_id()

2018-09-26T06:33:58+00:00

[ Upstream commit cd0e0ca69109d025b1a1b6609f70682db62138b0 ] The ARRAY_SIZE() macro is type size_t. If s6e8aa0_dcs_read() returns a negative error code, then "ret < ARRAY_SIZE(id)" is false because the negative error code is type promoted to a high positive value.

drm/panel: simple: Add missing panel_simple_unprepare() calls

2017-12-05T10:20:47+00:00

commit f3621a8eb59a913612c8e6e37d81f16b649f8b6c upstream. During panel removal or system shutdown panel_simple_disable() is called which disables the panel backlight but the panel is still powered due to missing calls to panel_simple_unprepare().
