mmc: core: fix power class selection
mmc_select_powerclass() function returns error if eMMC VDD level supported by host is between 2.7v to 3.2v. According to eMMC specification, valid voltage for high voltage cards is 2.7v to 3.6v. This patch ensures that 2.7v to 3.6v VDD range is treated as valid range. Also, failure to set the power class shouldn't be treated as fatal error because even if setting the power class fails, card can still work in default power class. If mmc_select_powerclass() returns error, just print the warning message and go ahead with rest of the card initialization. Signed-off-by:Subhash Jadavani <subhashj@codeaurora.org> Acked-by:
