crypto: tcrypt - Add debug prints
tcrypt is very tight-lipped when it succeeds, but a bit more feedback
would be useful when developing or debugging crypto drivers, especially
since even a successful run ends with the module failing to insert. Add
a couple of debug prints, which can be enabled with dynamic debug:
Before:
# insmod tcrypt.ko mode=10
insmod: can't insert 'tcrypt.ko': Resource temporarily unavailable
After:
# insmod tcrypt.ko mode=10 dyndbg
tcrypt: testing ecb(aes)
tcrypt: testing cbc(aes)
tcrypt: testing lrw(aes)
tcrypt: testing xts(aes)
tcrypt: testing ctr(aes)
tcrypt: testing rfc3686(ctr(aes))
tcrypt: all tests passed
insmod: can't insert 'tcrypt.ko': Resource temporarily unavailable
