From: Florian Fainelli <f.fainelli@gmail.com>
Subject: [PATCH v3 3/9] mtd: rawnand: brcmnand: Avoid pdev in brcmnand_init_cs()
Date: Fri, 07 Jan 2022 10:46:08 -0800
Content-Type: text/plain; charset="utf-8"

In preparation for encapsulating more of what the loop calling
brcmnand_init_cs() does, avoid using platform_device when it is the
device behind platform_device that we are using for printing errors.

No functional changes introduced.
