From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently, ret is being checked for an error condition however it
is not being assigned in the previous statement on the call of
function mipi_dsi_dcs_exit_sleep_mode. Add in the missing assignment
of ret.
Detected by CoverityScan, CID#1470174, 1470178 ("Unchecked return value")
Fixes: 26aec25593c2 ("drm/panel: Add Ilitek ILI9881c panel driver")
