    s390/qeth: sanitize strings in debug messages · e19e5be8
    Julian Wiedmann authored
    As Documentation/s390/s390dbf.txt states quite clearly, using any
    pointer in sprinf-formatted s390dbf debug entries is dangerous.
    The pointers are dereferenced whenever the trace file is read from.
    So if the referenced data has a shorter life-time than the trace file,
    any read operation can result in a use-after-free.
    
    So rip out all hazardous use of indirect data, and replace any usage of
    dev_name() and such by the Bus ID number.
