Subject: [RFC PATCH 2/2] eeprom: at25: make FRAM device ID error message more precise
Date: Tue, 1 Apr 2025 15:30:48 +0200 [thread overview]
Message-ID: <20250401133148.38330-3-m.heidelberg@cab.de> (raw)
In-Reply-To: <20250401133148.38330-1-m.heidelberg@cab.de>
The error description would be wrong in case the "size" Devicetree
property is missing for an FRAM without device ID.
Signed-off-by: Markus Heidelberg <m.heidelberg@cab.de>
