crypto: tcrypt - Use pr_cont to print test results
For some test cases, a line break gets inserted between the test banner
and the results. For example, with mode=211 this is the output:
[...]
testing speed of rfc4106(gcm(aes)) (rfc4106-gcm-aesni) encryption
[...] test 0 (160 bit key, 16 byte blocks):
[...] 1 operation in 2373 cycles (16 bytes)
--snip--
[...]
testing speed of gcm(aes) (generic-gcm-aesni) encryption
[...] test 0 (128 bit key, 16 byte blocks):
[...] 1 operation in 2338 cycles (16 bytes)
Similar behavior is seen in the following cases as well:
modprobe tcrypt mode=212
modprobe tcrypt mode=213
modprobe tcrypt mode=221
modprobe tcrypt mode=300 sec=1
modprobe tcrypt mode=400 sec=1
This doesn't happen with mode=215:
[...] tcrypt:
testing speed of multibuffer rfc4106(gcm(aes)) (rfc4106-gcm-aesni) encryption
[...] tcrypt: test 0 (160 bit key, 16 byte blocks): 1 operation in 2215 cycles (16 bytes)
--snip--
[...] tcrypt:
testing speed of multibuffer gcm(aes) (generic-gcm-aesni) encryption
[...] tcrypt: test 0 (128 bit key, 16 byte blocks): 1 operation in 2191 cycles (16 bytes)
This print inconsistency is because printk() is used instead of pr_cont()
in a few places. Change these to be pr_cont().
checkpatch warns that pr_cont() shouldn't be used. This can be ignored in
this context as tcrypt already uses pr_cont().
