Subject[PATCH 3/4] x86/crypto: serpent: Fix function prototypes
Date
Convert the use of 'struct serpent_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 serpent_ctx *'.
