Subject: V4L/DVB (10314): cx25840: ignore TUNER_SET_CONFIG in the command callback.
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=6d9f13c47a009ccbaf40c2e388ab349690dd8000;p=linux-2.6-omap-h63xx.git

V4L/DVB (10314): cx25840: ignore TUNER_SET_CONFIG in the command callback.

These days TUNER_SET_CONFIG is broadcast to the other i2c devices
and that triggers a fw load on the cx25840. Ignore this command
since cx25840 isn't a tuner and you really do not want to load
the firmware that early.
