Subject: [PATCH 4.4 24/32] usb: musb: host: correct cppi dma channel for isoch transfer
Date: Wed, 6 Jul 2016 18:19:34 -0700 [thread overview]
Message-ID: <20160707011627.473312586@linuxfoundation.org> (raw)
In-Reply-To: <20160707011626.475554429@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bin Liu <b-liu@ti.com>
commit 04471eb8c3158c0ad9df4b24da845a63b2e8f23a upstream.
Incorrect cppi dma channel is referenced in musb_rx_dma_iso_cppi41(),
which causes kernel NULL pointer reference oops later when calling
cppi41_dma_channel_program().
Fixes: 069a3fd (usb: musb: Remove ifdefs for musb_host_rx in musb_host.c
part1)
