Title
drm/panel: ili9341: fix optional regulator handling
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/panel: ili9341: fix optional regulator handling If the optional regulator lookup fails, reset the pointer to NULL. Other functions such as mipi_dbi_poweron_reset_conditional() only do a NULL pointer check and will otherwise dereference the error pointer.
