Subject: [PATCH] usb/peak_usb: cleanup code
Date: Tue, 10 May 2022 23:38:38 -0700	[thread overview]
Message-ID: <20220511063850.649012-1-zhaojunkui2008@126.com> (raw)

The variable fi and bi only used in branch if (!dev->prev_siblings)
, fi & bi not kmalloc in else branch, so move kfree into branch
if (!dev->prev_siblings),this change is to cleanup the code a bit.
