Subject: [PATCH 1/4] mtd: rawnand: meson: use struct_size macro
Date: Fri, 12 Apr 2019 00:00:53 +0200	[thread overview]
Message-ID: <20190411220056.19109-2-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20190411220056.19109-1-martin.blumenstingl@googlemail.com>

Use the recently introduced struct_size macro instead of open-coding
it's logic.
No functional changes.
