mmc: block: fix free of uninitialized 'idata->buf' Set 'idata->buf' to NULL so that it never gets returned without initialization. This fixes a bug where mmc_blk_ioctl_cmd() would free both 'idata' and 'idata->buf' but 'idata->buf' was returned uninitialized. Fixes: 1ff8950c0433 ("mmc: block: change to use kmalloc when copy data from userspace") Signed-off-by: Ville Viinikka <ville@tuxera.com> Cc: <stable@vger.kernel.org> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
