drm/panel: ilitek-ili9881c: do not fail probe if iovcc is absent

2026-07-22T14:17:08Z

Commit 4c95b2b7d49e ("drm/panel: ilitek-ili9881c: support Waveshare 7.0" DSI panel") adds an additional iovcc regulator that other Ilitek ili9881c based panels apparently do not have or need. The commit goes out of its way to make usage of this new regulator optional, dutifully testing if the field in `struct ili9881c` is NULL before touching the new regulator. However, in the probe function, it unconditionally fails if devm_regulator_get_optional returns an error. devm_regulator_get_optional() returns -ENODEV if the regulator is missing, causing probe to fail for other panels that do not have an iovcc-supply set in the device tree.
