mmc: block: don't use CMD23 with very old MMC cards
CMD23 aka SET_BLOCK_COUNT was introduced with MMC v3.1. Older versions of the specification allowed to terminate multi-block transfers only with CMD12. The patch fixes the following problem: mmc0: new MMC card at address 0001 mmcblk0: mmc0:0001 SDMB-16 15.3 MiB mmcblk0: timed out sending SET_BLOCK_COUNT command, card status 0x400900 ... blk_update_request: I/O error, dev mmcblk0, sector 0 Buffer I/O error on dev mmcblk0, logical block 0, async page read mmcblk0: unable to read partition table Signed-off-by: Daniel Glöckner <dg@emlix.com> Cc: <stable@vger.kernel.org> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
