Subject: omap_hsmmc: cater for weird CMD6 behaviour
From: Adrian Hunter <[email protected]>
Sometimes the controller unexpectedly produces a TC (transfer complete)
interrupt before the CC (command complete) interrupt for command 6
(SWITCH). This is a problem because the CC interrupt can get mixed up
with the next request. Add a hack for CMD6.
