Subject: [PATCH 0/3] [media] cx231xx: cleanup i2c adapter handling

Hi!

This seems like fairly straight forward cleanups/bugfixes. I don't
have the hardware and found the issues by reading code while doing
other things. So, it builds for me, but it's untested.

1/3 changes behavior on failure, but I think it's the right thing
to do. If it isn't for some reason, then the current code is crap
anyway, because as-is it compares with a value that is always zero
meaning that the entire "if (0 != bus->i2c_rc)"-clause with its
dev_warn can be removed from cx231xx_i2c_register.

Cheers,
Peter
