[PATCH v2] staging: ccree: remove unused function argument

From: Gilad Ben-Yossef
Date: Sun May 14 2017 - 02:36:29 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

"gcc -Wunused" warns about one argument being assigned but not used:

drivers/staging/ccree/ssi_cipher.c: In function 'ssi_blkcipher_complete':
drivers/staging/ccree/ssi_cipher.c:747:41: error: parameter 'info' set but not used [-Werror=unused-but-set-parameter]

We can simply drop that argument here and in its callers.

Fixes: 302ef8ebb4b2 ("staging: ccree: add skcipher support")
