Subject: mmc: sdhci: Allow override of get_cd() called from sdhci_request()

From: Adrian Hunter <[email protected]>

commit 8d28b7a72fe18bcdcdb047243ba8fec36b149955 upstream.

Drivers may need to provide their own get_cd() mmc host op, but currently the internals of the current op (sdhci_get_cd()) are provided by sdhci_do_get_cd() which is also called from sdhci_request().

To allow override of the get_cd functionality, change sdhci_request() to call ->get_cd() instead of sdhci_do_get_cd().

Note, in the future the call to ->get_cd() will likely be removed from sdhci_request() since most drivers don't need actually it. However this change is being done now to facilitate a subsequent bug fix.
