ctf_save_write's second parameter is gdb_byte *, and all these
arguments are 'char *'.  Since this function is ultimately just
writing host bytes to a local file with fwrite, an alternative would
be to change ctf_save_write to take a 'void *' instead of 'gdb_byte
*', thus removing the need for any cast (we have more calls with casts
than without).

	* ctf.c (ctf_write_uploaded_tsv, ctf_write_uploaded_tp): Add casts
	to 'gdb_byte *'.
