Subject: xentrace: Remove unneeded cast when assigning pointer value to dst
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=f94fcdbf7f4946952f9c22af307b10b088724a15;p=xen.git

xentrace: Remove unneeded cast when assigning pointer value to dst

Remove unneeded cast when assigning pointer value to dst.
Both arrays are uint32_t and memcpy takes a void pointer.
