From: Ian Abbott Date: Fri, 8 Jun 2012 09:40:05 +0000 (+0100) Subject: staging: comedi: amplc_pci230: Replace NULLFUNC X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=83afda9d449c61b55881d50465833784d8fda786;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git staging: comedi: amplc_pci230: Replace NULLFUNC The source code defines a macro NULLFUNC #define NULLFUNC 0 and uses it as a generic null function pointer constant. This is superfluous. Just use NULL instead.
