Subject: mmc: tmio: Fix tuning flow
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a8f399f624e1ae902828ad788f3601ff7b3e0eed;p=linux.git

mmc: tmio: Fix tuning flow

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.
