Subject: [PATCH v2] bluetooth: bcm203x: update the reference count of udev
Date: Sat, 31 Jul 2021 16:41:02 +0100	[thread overview]
Message-ID: <20210731154102.GA908767@pc> (raw)

Use usb_get_dev() to increment the reference count of the usb device
structure in order to avoid releasing the structure while it is still in
use. And use usb_put_dev() to decrement the reference count and thus,
when it will be equal to 0 the structure will be released.
