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[].
