mmc: core: check for zero length ioctl data If the read or write buffer size associated with the command sent through the mmc_blk_ioctl is zero, do not prepare data buffer. This enables a ioctl(2) call to for instance send a MMC_SWITCH to set a byte in the ext_csd. Signed-off-by: Johan Rudholm <johan.rudholm@stericsson.com> Signed-off-by: Chris Ball <cjb@laptop.org>
