Subject: mmc: sunxi: constify mmc_host_ops structures
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1f8029c3a1c6d5be547d9191e1ea1f3f56164e74;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mmc: sunxi: constify mmc_host_ops structures

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.
