Subject: mmc: s3cmci: Drop redundant code in s3cmci_setup_data()
X-Git-Tag: baikal/aarch64/sdk6.1~9247^2~124
X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=ac1ce7e9b996384afbdc2583e61280e274099253;p=kernel.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.
