Someone familiar with the driver/media/rc/imon.c file needs to figure out how rc_g_keycode_from_table() can be called with a NULL first argument: ictx->rdev is NULL when rc_g_keycode_from_table(ictx->rdev,...) is called. There might be some race at driver initialization, given that at first look ictx-rdev being NULL seems impossible. Your stack backtraces always indicate some sort of IRQ context, so maybe that matters.
