Dan Carpenter 2f9cd85882 drm/panel: type promotion bug in s6e8aa0_read_mtp_id()

[ Upstream commit cd0e0ca691 ]

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.
