Subject: stmmac: display the descriptors if DES0 = 0
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8be0328e52dc2c8c6f61563c9ccc95ae4d63e9ce;p=linux-beck.git

stmmac: display the descriptors if DES0 = 0

It makes sense to display the descriptors even if
DES0 is zero. This helps for example in case of it
is needed to dump rx write-back descriptors to get
timestamp status.
