| |
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Girish K S <girish.shivananjappa@linaro.org>
commit 913047e9e5787a90696533a9f109552b7694ecc9 upstream.
This patch fixes the wrong comparison before setting the interface voltage in DDR mode.
The assignment to the variable ddr before comaprison is either ddr = MMC_1_2V_DDR_MODE; or ddr == MMC_1_8V_DDR_MODE. But the comparison is done with the extended csd value if ddr == EXT_CSD_CARD_TYPE_DDR_1_2V.
