Subject: [media] tvp5150: propagate I2C write error in .s_register callback
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=eca4ca84a965d7fcc3430439898d0728818edc56;p=linux-beck.git

[media] tvp5150: propagate I2C write error in .s_register callback

The tvp5150_write() function can fail so don't return 0 unconditionally
in tvp5150_s_register() but propagate what's returned by tvp5150_write().
