Subject: crypto: testmgr - Allow implementation-specific tests
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a68f6610d4f1ebe61818f5926fa8fa9e75d06a95;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

crypto: testmgr - Allow implementation-specific tests

This patch adds the support for testing specific implementations.
This should only be used in very specific situations.  Right now
this means specific implementations of random number generators.
