解决办法一: make menuconfig,依次进入 Device Drivers GPIO Surport I2C GIPO Expanders 键盘按下y选中PCA95[357]X后,exit到上一次保存;再进入I2C GIPO Expanders选中终端控制器,一直exit保存 解决办法二: …
The separate struct bgpio_chip has been a pain to handle, both by being confusingly similar in name to struct gpio_chip and for being contained inside a struct so that struct gpio_chip is contained in a struct contained in a struct, making several steps of dereferencing necessary. Make thi...
