Subject: iommu: Do not initialise global vars explicitly to zero.
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~13159
X-Git-Url: https://dgit.raspbian.org/%22http:/www.example.com/cgi/%22https:/%22bookmarks://%22Dat/%22http:/www.example.com/cgi/%22https:/%22bookmarks:/%22Dat?a=commitdiff_plain;h=a7a8dc9942ca7c22d931751e9def47c76471dcbb;p=xen.git

iommu: Do not initialise global vars explicitly to zero.

Unnecessary and prevents them being allocated in BSS rather than data.
