Subject: [media] em28xx: prefer_bulk parameter is read-only
X-Git-Tag: v3.9-rc5~2^2~420
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b5cff595bd005dba8051e9125f0ed28b5ff05c89;p=platform%2Fkernel%2Flinux-exynos.git

[media] em28xx: prefer_bulk parameter is read-only

As the bulk mode is set at device's probe, it is not possible
to change it later. So, change the parameter to be read only
after modprobing.
