[RFT 6/6] mmc: tmio: remove indirection of 'execute_tuning' callback

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



After all the previous refactorization, we can now populate mmc_ops
directly and don't need a layer inbetween. The NULL-pointer check and
the error printout are already done by the MMC core.
