Subject: [media] tm6000: bugfix data check
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=edcfdd919a1c8afbf500be0dbfa9b68f40b4c219;p=deliverable%2Flinux.git

[media] tm6000: bugfix data check

beholder use a map with 3 bytes, but many rc maps have 2 bytes, so I add a workaround for beholder rc.
