[PATCH] x86/hw-breakpoints: eliminate a compiler warning for hw_breakpoint.c

From: Chen Yucong
Date: Mon Dec 29 2014 - 01:49:29 EST

There is a warning message when we compile the linux-next tree.

arch/x86/kernel/hw_breakpoint.c: In function âarch_validate_hwbkpt_settingsâ:
arch/x86/kernel/hw_breakpoint.c:329:20: warning: âalignâ may be used uninitialized in this function [-Wuninitialized]

This patch aims to eliminate the above compiler warning.
