[PATCH 6.18 02/52] usb: gadget: f_hid: Add missing error code

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ethan Tidmore <ethantidmore06@gmail.com>

[ Upstream commit 2c863dbbeac7b919d4634ad886978a6731916de3 ]

Currently in cdev_alloc() error path no error code is assigned.

Assign error code '-ENOMEM'.

Detected by Smatch:
drivers/usb/gadget/function/f_hid.c:1291 hidg_bind()
warn: missing error code 'status'

Fixes: 81ebd43cc0d6d ("usb: gadget: f_hid: don't call cdev_init while cdev in use")
