我在 Linux 内核 v4.14.98 中使用 tcan4x5x 驱动程序，我面临以下问题

[ 27.788175] tcan4x5x spi0.0: Unsupported version number: 0

[ 29.088498] tcan4x5x spi0.0: Probe failed, err=-22
[ 29.097673] tcan4x5x: probe of spi0.0 failed with error -22

我该如何解决这个问题？

建议启用动态调试控制并检查是否有更多关于错误 EINVAL 错误 22 的信息。

  • echo -n '+p' > /sys/kernel/debug/dynamic_debug/control
  • 再次卸载和加载驱动程序
