Ooop...will fix. > - I do not understand why kfifo is needed The firmware and the host would conflict by read command and finger report simultaneously. So I'm simply using kfifo in IRQ thread function. * read command: writing 4 bytes commands and the device asserts GPIO interrupt and then response 4 bytes data. There was an error if we do not use kfifo: With heavy loading by finger report / read command, the driver may get finger report as response data.
