MLK-10453 mmc: fix possible unintialized ocr
This commit ca4113da25b42bce44a2e7998966a47352f11613 "mmc: fix OCR Polling" does not consider cmd structure, and may leave it in uninitialized state. We can directly use op_cond_response here, since until here, op_cond_response already get the OCR value from chip. Signed-off-by: Peng Fan <Peng.Fan@freescale.com> Suggested-by: Ye.Li <B37916@freescale.com> (cherry picked from commit a033d2d43904f27778ee6a44f3e35494f9f72152)
