Subject: [PATCH 2/4] x86/crypto: cast6: Fix function prototypes
Convert the use of 'struct cast6_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.
