-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!
