Subject: [PATCH 10/23] em28xx: create a common function for isoc and bulk USB transfer initialization
Date: Sun, 21 Oct 2012 19:52:15 +0300	[thread overview]
Message-ID: <1350838349-14763-11-git-send-email-fschaefer.oss@googlemail.com> (raw)
In-Reply-To: <1350838349-14763-1-git-send-email-fschaefer.oss@googlemail.com>

- rename em28xx_init_isoc to em28xx_init_usb_xfer
- add parameter for isoc/bulk transfer selection which is passed to em28xx_alloc_urbs
- rename local variable isoc_buf to usb_bufs
