[PATCH] Revert "mmc: mxs: fix card detection in case of 'broken-cd' flag set"

From: Michael Thalmeier
Date: Wed Oct 24 2018 - 10:18:32 EST


This reverts commit 6f726f495f2d ("mmc: mxs: fix card detection in case of 'broken-cd' flag set").

Since mxs_mmc_probe always sets MMC_CAP_NEEDS_POLL unconditionally, card
detect is not working properly any more since commit 6f726f495f2d.
Instead of querying the card detect status mxs_mmc_get_cd now always
returns 1 which causes probing commands being sent to the mmc card.

The expected behaviour of commit 6f726f495f2d should be reachable by setting
broken_cd instead.
