+Subject: [PATCH] mmc: mxs: fix card detection function for broken card detect
+
+Return -ENOSYS in get_cd if broken-cd is specified in the device tree.
+
+Commit a91fe279ae75 (mmc: mxs: use standard flag for broken card
+detection) sets MMC_CAP_NEEDS_POLL when broken-cd is specified. This
+driver sets this flag unconditionally as it does not support a card
+detect interrupt. Instead, broken-cd means that there is no card detect
+signal connected.
+
+The mmc core checks the get_cd function return value to determine if a
+card is present. Only for a non-zero return value it will attempt to
+initialize the card. So retuning -ENOSYS will allow the card to be
+initialized.
+
+For comparison, mmc_gpio_get_cd in slot-gpio.c also returns -ENOSYS if
+the card detect GPIO is not valid.
