Hi,

issue: after reload the spi module, it can't do SPI communication.

We have faced issue when execute the following command.
insmod xxx.ko(Then, /dev/spidev0.0 is created with success)
rmmod xxx.ko (Then, /dev/spidev0.0 is deleted with success)
insmod xxx.ko(Then, /dev/spidev0.0 is created, however, below error message is showed)

  0000:02:0c.1: registered master spi0
  0000:02:0c.1: chipselect 0 already in use
  0000:02:0c.1: can't create new device for spidev

Do you have any information about the above ?

kernel=2.6.37 on FC14

With Best Regards,
