[patch v2] net/fec: cleanup types in fec_get_mac()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



My static checker complains that on some arches unsigned longs can be 8
characters which is larger than the buffer is only 6 chars.
Additionally, Ben Hutchings points out that the buffer actually holds
big endian data and the buffer we are reading from is CPU endian.

v2: fix endian annotations and reverse the beXX_to_cpu() calls so that
    they say cpu_to_beXX().
