(so, host->ops was not set by any drivers except bcm2835_sdhci.c) Now, we have more optional callbacks, get_cd, set_control_reg, and set_clock. However, the code if (host->ops->get_cd) host->ops->get_cd(host); ... expects host->ops is set for all drivers. Commit 5e96217f0434 ("mmc: pic32_sdhci: move the code to pic32_sdhci.c") and commit 62226b68631b ("mmc: sdhci: move the callback function into sdhci_ops") added sdhci_ops for pic32_sdhci.c and s5p_sdhci.c, but the other drivers still do not (need not) set host->ops because all callbacks in sdhci_ops are optional. host->ops must be checked to avoid the system crash caused by NULL pointer access.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some MMC drivers describe operations with the DM_MMC_OPS form, but there are still several drivers with older implementation. We can not compile drivers from different groups at the same time because the core framework is shared with #ifdef CONFIG_DM_MMC_OPS. Every driver should have "depends on DM_MMC_OPS" (or !DM_MMC_OPS) explicitly to express which framework it is based on. This will avoid enabling drivers with incompatible interface at the same time. It is incorrect to make a driver "select DM_MMC_OPS". While we are here, add "depends on OF_CONTROL" as well because this driver can be configured only by Device Tree.
