2014-06-23usb: free up composite gadget string ids on unbindRakesh Bodla
There are only 254 USB composite gadget string_ids available. When switching gadget mode such as mtp and acm repeatedly, they will be exhausted. This bug has been brought up since android composite driver introduced a way to switch gadget modes while the composite driver is still holding its bind. Fix this by reset next_string_id and clean up gstrings when android gadgets are disabled. Also by removing the condition comparing gadgets' string id to 0 because gadget string id has to be re-assigned whenever the string count is reset. The codes removed the condition check will work as the same as before they have changed if the gadgets are used by other composite drivers other than android since all of them call bind only once and never unbind it hence no side effects considered.

commit 2d1f7af3d60dd09794e0738a915d272c6c27abc5 upstream. 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.

2014-02-13fix false disconnect due to a signal sent to the reading processkeunyoung
- In the current implementation, when a signal is sent to the reading process, read is cancelled by calling usb_ep_dequeue, which lead into calling acc_complete_out with ECONNRESET, but the current logic treats it as disconnection, which makes the device inaccessible until cable is actually disconnected. - The fix calls disconnect only when ESHUTDOWN error is passed. - If data has already arrived while trying cancelling, the data is marked as available, and it will be read out on the next read. This is necessary as USB bulk is assumed to guarantee no data loss. Signed-off-by: keunyoung <keunyoung@google.com>
