Subject: [PATCH] x86/hw-breakpoints: eliminate a compiler warning for hw_breakpoint.c
Date: Mon, 29 Dec 2014 14:49:23 +0800 [thread overview]
Message-ID: <1419835763-13241-1-git-send-email-slaoub@gmail.com> (raw)
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.
