[PATCH] staging: pi433: rf69.c: Introduced define DEBUG_FUNC_ENTRY

From: Marcus Wolf
Date: Sat Dec 02 2017 - 06:46:04 EST


Since dev_dbg already depends on define DEBUG, there was no sense, to enclose
dev_dbg lines with #ifdef DEBUG.
Instead of removing #ifdef DEBUG, I introduced define DEBUG_FUNC_ENTRY. So now it is
possible to switch of the function entry debug lines even while debug is switched on.
