Subject: [media] tvp7002: remove dv_preset support
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=416d307651ffa035a1e9f5ccc9f915cb2235d415;p=openwrt%2Fstaging%2Fblogic.git

[media] tvp7002: remove dv_preset support

Finally remove the dv_preset support from this driver. Note that dv_preset
support was already removed from any bridge drivers that use this i2c
driver, so the dv_preset ops were no longer called and can be removed
safely.
