[PATCH 06/12] mmc: toshsd: constify mmc_host_ops structures
From: Julia Lawall
Date: Sat Jul 29 2017 - 02:26:34 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.
