返回类型：void

参数：

类型参数名称
struct kobj_uevent_env *env
420  modalias_prefix[]等于"MODALIAS="
424  以i小于envp_idx循环
425  如果字符串指定长度比较则
427  i自加
428  继续下一循环
431  len等于strlen(envp[i])加1
433  如果i不等于envp_idx减1则
434  memmove(envp[i], envp[i + 1], buflen - len)
437  以j小于envp_idx减1循环envp[j]等于envp[j + 1]减len
441  envp_idx自减
442  buflen减等于len
