Subject: [PATCH] usb: storage: make disk cdev name configurable via Kconfig
Date: Tue, 23 Jun 2026 10:26:46 -0400 [thread overview]
Message-ID: <20260623142646.87173-1-chalianis1@gmail.com> (raw)
From: Anis Chali <anis.chali@ro-main.com>
Add USBDISK_NAME string option to allow customizing the USB storage
device name, defaulting to "disk" to preserve existing behaviour.
