Subject: crypto: omap - add omap_sham_unregister_algs helper
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c3494e6fbb35579a131de11369b658a59b1323e5;p=thirdparty%2Fkernel%2Flinux.git

crypto: omap - add omap_sham_unregister_algs helper

Add a new helper omap_sham_unregister_algs() and replace two for loops
in omap_sham_probe() and omap_sham_remove(), which also ensure
->registered is reset to 0.
