Subject: mmc: s3cmci: Drop redundant code in s3cmci_setup_data()
X-Git-Tag: v5.10.7~2504^2~124
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f51167c010ea848160c01aa90ed172d8f569c27c;p=platform%2Fkernel%2Flinux-rpi.git

mmc: s3cmci: Drop redundant code in s3cmci_setup_data()

The in-parameter struct mmc_data *data is never NULL, because the caller
always provides a valid pointer. Hence drop the corresponding redundant
code.
