| |
A failure of sahara_hw_descriptor_create() with -EINVAL due to scatter list out of bounds/invalid would not be reported back. This patch just passes on the -EINVAL so it is visible in sahara_queue_manage().
Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org> ---
v2: cut&past error - the condition is not if (!ret) but if (ret) as sahara_hw_descriptor_create() will return 0 on success and -EINVAL in all failure paths.
Patch was only compile tested with imx_v4_v5_defconfig CONFIG_CRYPTO_HW=y, CONFIG_CRYPTO_DEV_SAHARA=m
Patch is against 3.19.0-rc7 (localversion-next is -next-20150204)
