[PATCH RFC] crypto: testmgr drop wrong init_completion

[PATCH RFC] crypto: testmgr drop wrong init_completion

[Nicholas Mc Guire]

init_completion() is called here to reinitialize a completion object
that was already re-initialized in wait_async_op() by 
reinit_completion() if complete (via tcrypt_complete()) had been called
and wait_for_completion() returned, so no need to reinit it here.


Fixes: commit 946cc46372dc ("crypto: testmgr - add tests vectors for RSA")

Found by experimental coccinelle script
./crypto/testmgr.c:2174:1-16: WARNING: possible duplicate init_completion

Only based on code review and no testing. In case I am overlooking something
and the re-initialization of the completion object is actually needed it
should be using reinit_completion() and not init_completion() anyway.
But as wait_async_op() will leave with the completion object re-initialized
it really should not be needed here (found no path in between that could
have called completion()).

Patch was only compile tested with: x86_64_defconfig (implies cryptomgr-y)

Patch is against linux-4.10-rc6 (localversion-next is next-20170210)
