From e614740a063ff8a87930861674e64347d4b091ba Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Thu, 15 Apr 2021 10:44:12 +0200 Subject: mmc: sdhci-s3c: constify uses of driver/match data The driver data (struct sdhci_s3c_drv_data) stored in of_device_id table is allocated as const and used only in const-way. Skip unnecessary const-away casts and convert all users to work with pointer to const. This is both more logical and safer.
