Subject: [media] tvp514x: Fix init seqeunce
X-Git-Tag: v3.11-rc1~17^2~18
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f0a12d0c9272ae24491b983c4982acdacdac1baf;p=profile%2Fivi%2Fkernel-x86-ivi.git

[media] tvp514x: Fix init seqeunce

client->driver->id_table will always point to the first entry in the device id
table. So all devices will use the same init sequence. Use the id table entry
that gets passed to the driver's probe() function to get the right init
sequence.
