I agree. A modified patch will be sent right after. Thanks for your comment. >> + >> return err; >> } >> > >Kind regards >Uffe

The switch failure message in mmc_select_timing had been removed since that is invalid: commit 0400ed0a083a ("mmc: core: remove the invalid message in mmc_select_timing") Now, in the case when mmc_select_hs return error in mmc_select_timing, there is nothing to print failure message. Let's make for mmc_select_hs() print message itself in the failure case.
