crypto: marvell/cesa - Fix type mismatch warning
Commit df8fc4e934c1 ("kbuild: Enable -fstrict-flex-arrays=3") uncovered
a type mismatch in cesa 3des support that leads to a memcpy beyond the
end of a structure:
In function 'fortify_memcpy_chk',
inlined from 'mv_cesa_des3_ede_setkey' at drivers/crypto/marvell/cesa/cipher.c:307:2:
include/linux/fortify-string.h:583:25: error: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning]
583 | __write_overflow_field(p_size_field, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is probably harmless as the actual data that is copied has the correct
type, but clearly worth fixing nonetheless.
