mmc/card/block.c : mmc_blk_open readonly mount bug?

[sasin]

mmc_block_open increments md->usage although it returns with -EROFS when
default mounting a MMC/SD card with write protect switch on.  This
reference counting bug prevents /dev/mmcblkX from being released on card
removal, and situation worsen with reinsertion until the minor number
range runs out.

"return -EROFS;"

should be replaced by

"
{
ret = -EROFS;
mmc_blk_put(md);
}
"


Best regards,
Sasi
