Subject: usb: musb: host: correct cppi dma channel for isoch transfer
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)
