From: Daniele Di Proietto <redacted> This change, firstly, avoids declaring the formal parameter const, since it is treated as non const. (to avoid -Wcast-qual) Secondly, it cast the pointer from void* to u8*, since it is used in arithmetic (to avoid -Wpointer-arith) Signed-off-by: Daniele Di Proietto <redacted> Signed-off-by: Jesse Gross <redacted> --- net/openvswitch/vport.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
