[PATCH v3 1/2] asm-generic/bug.h: declare struct pt_regs; before function prototype

From: Ian Abbott
Date: Tue May 23 2017 - 11:54:12 EST


The declaration of `__warn()` has `struct pt_regs *regs` as one of its
parameters. This can result in compiler warnings if `struct regs` is
not already declared. Add an empty declaration of `struct pt_regs` to
avoid the warnings.

v3: Actually, there was no v1 or v2. I called this v3 to match the
series.
