[PATCH 1/4] mmc: tmio: Fix tuning flow

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

 



From: Masaharu Hayakawa <masaharu.hayakawa.ry@xxxxxxxxxxx>

If the return value of mmc_send_tuning() is error other than -EILSEQ,
the tuning fails and process goes out of for_loop. The correct
processing is to judge their TAP as not good (NG) and continue.
