* usb: gadget: fsl_udc_core: dTD's next dtd pointer need to be updated once ↵Peter Chen2012-05-041-0/+2
| | | | | | | | | | | | | | | | | | | | | written dTD's next dtd pointer need to be updated once CPU writes it, or this request may not be handled by controller, then host will get NAK from device forever. This problem occurs when there is a request is handling, we need to add a new request to dTD list, if this new request is added before the current one is finished, the new request is intended to added as next dtd pointer at current dTD, but without wmb(), the dTD's next dtd pointer may not be updated when the controller reads it. In that case, the controller will still get Terminate Bit is 1 at dTD's next dtd pointer, that means there is no next request, then this new request is missed by controller.

* usb: gadget: composite: prevent a memory leak when configuration bind failsYongsul Oh2012-05-041-0/+13
| | | | | | | | | | | | | | | | | | | | | | In some USB composite gadget drivers, the configuration's bind function called by the usb_add_config() calls multiple bind config functions. (for example cdc2 configuration bind function in the cdc_do_config() of the cdc2.c has two functionality bind config functions. - the ecm_bind_config() & the acm_bind_config()) In each functionality bind config function, new instance is allocated and finally added by the usb_add_function(). So if an error occurred during the second functionality bind config (for example an error occurred at the acm_bind_config() after succeeding of the ecm_bind_function()), the instance created by the acm_bind_config() cannot be freed creating a memory leak. This patch fixes this issue. Signed-off-by: Yongsul Oh <yongsul96.oh@samsung.com> Acked-by: Michal Nazarewicz <mina86@mina86.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

* usb: gadget: dummy_hcd: allow to free requests on disabled endpointsSebastian Andrzej Siewior2012-05-041-5/+3
| | | | | | | | | | | | | ep->desc is set to NULL on endpoint disable. That means once an endpoint is disabled it is not possible to free requests. In my target gadget I first disable endpoints to make sure I have no requests on the fly and then free frequests. On dummy I am leaking memory here. Since I can't imagine a reason why it should be a bad thing, lets allow to free requests on disabled endpoints. On removal of composite the ep0 request is removed so lets allow that here as well.

This makes sense, but the implementation detail of calling mmc_card_is_removable() causes some problems, because mmc_card_is_removable() is overloaded with CONFIG_MMC_UNSAFE_RESUME semantics. In the OLPC XO case, we need CONFIG_MMC_UNSAFE_RESUME because our root filesystem is stored on SD, but we also have external SD card slots where we want automatic card detection. Refine the check to only apply to hosts marked as MMC_CAP_NONREMOVABLE, which is defined to mean that the card is *really* nonremovable. This could be revisited in future if we find a way to improve CONFIG_MMC_UNSAFE_RESUME semantics.

| * | mmc: dw_mmc: Fix switch from DMA to PIOSeungwon Jeon2012-04-211-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When dw_mci_pre_dma_transfer returns failure in some reasons, dw_mci_submit_data will prepare to switch the PIO mode from DMA. After switching to PIO mode, DMA(IDMAC in particular) is still enabled. This makes the corruption in handling interrupt and the driver lock-up.

| * | mmc: remove MMC bus legacy suspend/resume methodChuanxiao Dong2012-04-212-17/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MMC bus is using legacy suspend/resume method, which is not compatible if runtime pm callbacks are used. In this scenario, MMC bus suspend/resume callbacks cannot be called when system entering S3. So change to use the new defined dev_pm_ops for system sleeping mode. Tested on AM335x Platform.

| * | mmc: omap_hsmmc: Get rid of of_have_populated_dt() usageRajendra Nayak2012-04-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of_have_populated_dt() is not expected to be used in drivers but instead only in early platform init code. Drivers on the other hand should rely on dev->of_node or of_match_device(). Besides usage of of_have_populated_dt() also throws up build error as below which was reported by Balaji TK, when omap_hsmmc is built as a module. ERROR: "allnodes" [drivers/mmc/host/omap_hsmmc.ko] undefined! make[1]: *** [__modpost] Error 1 make: *** [modules] Error 2 So get rid of all of_have_populated_dt() usage in omap_hsmmc driver and instead use dev->of_node to make the same dicisions as earlier.
