Subject: drivers/net/tehuti: use proper capability check for raw IO access
X-Git-Tag: upstream/snapshot3+hdmi~25525
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6203554207728f43cfb9fd48585cd6500da73d42;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

drivers/net/tehuti: use proper capability check for raw IO access

Yeah, in practice they both mean "root", but Alan correctly points out
that anybody who gets to do raw IO space accesses should really be using
CAP_SYS_RAWIO rather than CAP_NET_ADMIN.
