Analyze and fix the following issue in the Linux kernel code: ata: libata: Improve __ata_qc_complete()
Problem Details: The function __ata_qc_complete() is always called with a qc that already has been dereferenced and so is guaranteed to be non-NULL (as otherwise the kernel would have crashed). So remove the warning for a NULL qc as it is useless. Furthermore, the qc passed to __ata_qc_complete() must always be marked...
