microblaze: Use unsigned return type in do_syscall_trace_enter
Registers are not signed types. The patch removes warnings: arch/microblaze/kernel/ptrace.c: In function 'do_syscall_trace_enter': arch/microblaze/kernel/ptrace.c:152:14: warning: signed and unsigned type in conditional expression [-Wsign-compare] return ret ?: regs->r12; Signed-off-by: Michal Simek <michal.simek@xilinx.com>
