Subject: [PATCH] mmc: core: remove the duplicate variable at ext_csd structure
Date: Fri, 15 Feb 2013 22:11:20 +0900 [thread overview]
Message-ID: <511E33F8.6090109@samsung.com> (raw)
Some ext_csd's variable have been defined the unnecessarily.
sec_erase_mult/sec_trim_mult/sec_feature_support would not be changed.
Then we can use the just "_raw_" variable.
