[PATCH] mmc/core: free mmc_card when cmd 3,9,7 got failed in mmc_sd_init_card

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Wei WANG <wei_wang@xxxxxxxxxxxxxx>

In function mmc_sd_init_card, if command 3/9/7 got failed, mmc_card
allocated just before won't be freed. This would cause memory leak.
