Subject: [PATCH v5 02/14] software node: introduce PROPERTY_ENTRY_ARRAY_XXX_LEN()
Date: Fri, 11 Oct 2019 16:07:09 -0700
Message-ID: <20191011230721.206646-3-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <20191011230721.206646-1-dmitry.torokhov@gmail.com>

Sometimes we want to initialize property entry array from a regular
pointer, when we can't determine length automatically via ARRAY_SIZE.
Let's introduce PROPERTY_ENTRY_ARRAY_XXX_LEN macros that take explicit
"len" argument.
