From 14a82ea7e1682645d942d9fb41fcb6126fd1645e Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Tue, 21 May 2019 09:06:30 +0200 Subject: mtd: rawnand: export NAND operation tracer The NAND core has a NAND operation tracing function, but it can only be used by drivers using the generic option parser from the NAND core. Export the tracing function as a static inline function in rawnand.h so that drivers implementing exec_op directly do not have to write their own operation tracing.
