There is a warning message when we compile the linux-next tree.
arch/x86/kernel/hw_breakpoint.c: In function ‘arch_validate_hwbkpt_settings’:
arch/x86/kernel/hw_breakpoint.c:329:20: warning: ‘align’ may be used uninitialized in this function [-Wuninitialized]
This patch aims to eliminate the above compiler warning.
