From 5289b5350ba5442cfcfbb18488b3a9d9e4f39ede Mon Sep 17 00:00:00 2001 From: Andrew Gabbasov Date: Thu, 19 Mar 2015 07:44:04 -0500 Subject: [PATCH] mmc: Do not pass external mmc_cmd structure to mmc_send_op_cond_iter() The previous change to use 'ocr' structure field for storing send_op_cond command response also stopped using command response directly outside of mmc_send_op_cond_iter(). Now it becomes possible to use command structure in mmc_send_op_cond_iter() locally, removing a necessity to pass it as an argument from the caller.
