[patch v2] sata, highbank: clear whole array in highbank_initialize_phys()

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

 




The original code used the wrong parameter to clear tx_atten[].  It
passed the number of elements instead of sizeof() the array to memset.

The other potential issue was that cphy_base[] wasn't cleared.  I'm not
sure if that was a real problem or not, but I have cleared it in my
patch.

Instead of using memset(), this patch uses empty initializers as a
cleanup.

v2: used {} initialization instead of memset.  I also just went ahead
    and cleared cphy_base[].
