For the others, this field value remain NULL by\ndefault.\nThe cancel_work_sync function is unconditionally called in\nmtk_jpeg_release function, even for the variants that do not use the\nworkqueue. This call generates a WARN_ON print in __flush_work because\nthe workqueue callback function presence check fails in __flush_work\nfunction (used by cancel_work_sync).\n\nSo, to avoid these warnings, call cancel_work_sync only if a workqueue\ncallback is defined in platform data."
