Subject: [PATCH V2] mtd: rawnand: brcmnand: propagate init error -EPROBE_DEFER up
Date: Wed, 19 Jul 2023 10:43:24 +0200	[thread overview]
Message-ID: <20230719084324.14799-1-zajec5@gmail.com> (raw)

From: Rafał Miłecki <rafal@milecki.pl>

MTD subsystem may return -EPROBE_DEFER if something isn't ready yet.
It's important to pass that error up so device will get probed later.

V2: Add of_node_put() - thanks Miquel!
