From: Arnd Bergmann <arnd@xxxxxxxx>
Using get_unaligned() on a u8 pointer is pointless, and will
result in a compiler warning after a planned cleanup:
In file included from arch/x86/include/generated/asm/unaligned.h:1,
from security/apparmor/policy_unpack.c:16:
security/apparmor/policy_unpack.c: In function 'unpack_u8':
include/asm-generic/unaligned.h:13:15: error: 'packed' attribute ignored for field of type 'u8' {aka 'unsigned char'} [-Werror=attributes]
13 | const struct { type x __packed; } *__pptr = (typeof(__pptr))(ptr); \
| ^
Simply dereference this pointer directly.
