Subject: [PATCH 01/10] linux/device.h: use unique identifier for each struct _ddebug
Date: Tue,  9 Apr 2019 23:25:08 +0200	[thread overview]
Message-ID: <20190409212517.7321-2-linux@rasmusvillemoes.dk> (raw)
In-Reply-To: <20190409212517.7321-1-linux@rasmusvillemoes.dk>

Changes on x86-64 later in this series require that all struct _ddebug
descriptors in a translation unit uses distinct identifiers. Realize
that for dev_dbg_ratelimited by generating such an identifier via
__UNIQUE_ID and pass that to an extra level of macros.

No functional change.
