[PATCH] checkpatch: add NOKPROBE_SYMBOL to the whitelist of lines that can occur immediately after functions

[Paul Walmsley]

It's customary for NOKPROBE_SYMBOL() macro usage to appear immedately
after a function's final closing brace, but checkpatch doesn't know
that yet.  As a result, checkpatch --strict incorrectly flags this
common kernel pattern, e.g.,

CHECK: Please use a blank line after function/struct/union/enum declarations
33: FILE: arch/riscv/kernel/traps.c:273:
 }
+NOKPROBE_SYMBOL(probe_single_step_handler);

Fix by adding NOKPROBE_SYMBOL to the whitelist of patterns that are
cleared to appear immediately after functions.
