+Subject: [PATCH] usb: gadget: bcm63xx_udc: fix build failure on DMA channel
+ code
+
+Commit 3dc6475 ("bcm63xx_enet: add support Broadcom BCM6345 Ethernet")
+changed the ENETDMA[CS] macros such that they are no longer macros, but
+actual register offset definitions. The bcm63xx_udc driver was not
+updated, and as a result, causes the following build error to pop up:
+
+ CC drivers/usb/gadget/u_ether.o
+drivers/usb/gadget/bcm63xx_udc.c: In function 'iudma_write':
+drivers/usb/gadget/bcm63xx_udc.c:642:24: error: called object '0' is not
+a function
+drivers/usb/gadget/bcm63xx_udc.c: In function 'iudma_reset_channel':
+drivers/usb/gadget/bcm63xx_udc.c:698:46: error: called object '0' is not
+a function
+drivers/usb/gadget/bcm63xx_udc.c:700:49: error: called object '0' is not
+a function
+
+Fix this by updating usb_dmac_{read,write}l and usb_dmas_{read,write}l to
+take an extra channel argument, and use the channel width
+(ENETDMA_CHAN_WIDTH) to offset the register we want to access, hence
+doing again what the macro implicitely did for us.

+Felipe,
+
+This is against your branch as balbi/usb.git, and this fix should be applied to
+stable 3.11 onwards.
+
+Thanks!
