| | | | | | | | | | | Those are enabled with W=1 make option. The patch leaves of some type-limits warnings which are caused by generic macros used in a way where they produce always-false conditions.

* usb: gadget: bdc_udc: fix race condition in bdc_udc_exit()Alexey Khoroshilov2016-03-041-0/+5
| | | | | | | | | | | | | | | bdc_ep_disable() expects to be called with bdc->lock held. The assumption is met in all the cases except for call from bdc_udc_exit(), that is called from bdc_remove(). As a result a race can happen or unheld bdc->lock can be unlocked in bdc_req_complete(). The patch proposes to acquire-release bdc->lock around bdc_ep_disable() in bdc_udc_exit().

* usb: gadget: bdc: fix memory leakSudip Mukherjee2015-09-301-1/+3
| | | | | | | | | | If dma_pool_alloc() fails we are jumping to fail and releasing all the bd_tables which have been added to the chain but we missed freeing this bd_table which was just allocated and still not added to the chain of bd_table.

| | | | | | | | | | | | | | | | Remove unneeded NULL test. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x; @@ -if (x != NULL) \(kmem_cache_destroy\|mempool_destroy\|dma_pool_destroy\)(x); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Felipe Balbi <balbi@ti.com>

MUSB also got support for building all DMA engines in one binary; this will be great for distros. DWC3 now has no trace of dev_dbg()/dev_vdbg() usage. We will rely solely on tracing to debug DWC3. There was also a fix for memory corruption with EP0 when maxpacket size transfers are > 512 bytes. Robert's EP capabilities flags is making EP selection a lot simpler. UDCs are now required to set these flags up when adding endpoints to the framework. Other than these, we have the usual set of miscelaneous cleanups and minor fixes.
