Subject: [PATCH] x86: suppress trivial sparse signedness warnings
Date: Tue, 23 Sep 2008 15:05:46 -0700	[thread overview]
Message-ID: <1222207546.16003.21.camel@brick> (raw)

Could just as easily change the three casts to cast to the correct
type...this patch changes the type of ftrace_nop instead.

Supresses sparse warnings:
arch/x86/kernel/ftrace.c:157:14: warning: incorrect type in assignment (different signedness)
arch/x86/kernel/ftrace.c:157:14:    expected long *static [toplevel] ftrace_nop
arch/x86/kernel/ftrace.c:157:14:    got unsigned long *<noident>
arch/x86/kernel/ftrace.c:161:14: warning: incorrect type in assignment (different signedness)
arch/x86/kernel/ftrace.c:161:14:    expected long *static [toplevel] ftrace_nop
arch/x86/kernel/ftrace.c:161:14:    got unsigned long *<noident>
arch/x86/kernel/ftrace.c:165:14: warning: incorrect type in assignment (different signedness)
arch/x86/kernel/ftrace.c:165:14:    expected long *static [toplevel] ftrace_nop
arch/x86/kernel/ftrace.c:165:14:    got unsigned long *<noident>
