Grant Grundler b093410c9a mmc: block: copy resp[] data on err for MMC_IOC_MULTI_CMD ... MMC_IOC_CMD and MMC_IOC_MULTI_CMD ioctl() code currently bails on any eMMC errors. However, in case there is any resp[] data, we should attempt to copy resp[] back to user space. The user app can then determine which command(s) failed in the MMC_IOC_MULTI_CMD case AND/OR report better diagnostics in both cases. Gwendal Grignou provided the idea and it was previously implemented and tested on v3.18 ChromeOS kernel: https://chromium-review.googlesource.com/#/c/299956 Signed-off-by: Grant Grundler <grundler@chromium.org> Reviewed-by: Hyung Taek Ryoo <hryoo@nvidia.com> Reviewed-by: Gwendal Grignou <gwendal@chromium.org> Tested-by: David Riley <davidriley@chromium.org> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>		2015-10-26 16:00:03 +01:00
