[PATCH 02/12] mmc: s3cmci: constify mmc_host_ops structures

From: Julia Lawall
Date: Sat Jul 29 2017 - 02:28:00 EST


The mmc_host_ops structure is only stored in the ops field of an
mmc_host structure, which is declared as const. Thus the mmc_host_ops
structure itself can be const.

Done with the help of Coccinelle.
