Subject: [PATCH 4/4] x86/crypto: twofish: Fix function prototypes
Date: Sun, 15 Apr 2018 01:15:42 -0300 [thread overview]
Message-ID: <20180415041542.5364-5-jmoreira@suse.de> (raw)
In-Reply-To: <20180415041542.5364-1-jmoreira@suse.de>
Convert the use of 'struct twofish_ctx *' to 'void *' in prototypes of
functions which are referenced through 'struct common_glue_func_entry',
making their prototypes match those of this struct and, consequently,
turning them compatible with CFI requirements.
Whenever needed, cast 'void *' to 'struct twofish_ctx *'.
