LSM: Fix type of id parameter in kernel_post_load_data prototype
Clang warns:
security/security.c:1716:59: warning: implicit conversion from
enumeration type 'enum kernel_load_data_id' to different enumeration
type 'enum kernel_read_file_id' [-Wenum-conversion]
ret = call_int_hook(kernel_post_load_data, 0, buf, size, id,
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~
security/security.c:715:22: note: expanded from macro 'call_int_hook'
RC = P->hook.FUNC(__VA_ARGS__); \
~ ^~~~~~~~~~~
1 warning generated.
There is a mismatch between the id parameter type in
security_kernel_post_load_data and the function pointer prototype that
is created by the LSM_HOOK macro in the security_list_options union. Fix
the type in the LSM_HOOK macro as 'enum kernel_load_data_id' is what is
expected.
