2013-08-27usb: phy: am335x-control: make it compile withSebastian Andrzej Siewior
Randy reported this |drivers/usb/phy/phy-am335x-control.c:45:3: error: implicit declaration |of function '__WARN' [-Werror=implicit-function-declaration] and left it as an excercice to figure out that this happens only with CONFIG_BUG=n. As a fix I replace it with WARN_ON(). And there is a space before return so fix this, too.

2013-08-27usb: gadget: configfs: keep a function if it is not successfully addedAndrzej Pietrasiewicz
If usb_add_function() fails then the currently processed function is already not in the list in struct config_usb_cfg, and neither is it in the list in struct usb_configuration. At the err_purge_funcs label the purge_config_funcs() is called, which iterates over all configurations, and in each configuration it iterates over all _successfully_ added functions, and moves them back from the list in struct usb_configuration to the list in struct config_usb_cfg. BUT the function which has just failed adding and caused the unwind process is not taken care of and is effectively lost. This patch modifies the configfs_composite_bind() function so that if the usb_add_function() fails, then the currently processed function is returned to the list in struct config_usb_cfg. It would be tempting to delay the list_del() in question after usb_add_function() invocation, but a struct list_head (&f->list) cannot be stored in more than one list at the same time, so the list_del() must be called before usb_add_function(). Hence, the solution is to list_add() after usb_add_function() in case of error.

The ata_dev_acpi_handle is defined in libata-acpi.c and the only external user is libata-zpodd.c, which is built when CONFIG_ATA_ACPI is set, so there is no need to make an empty stub function for ONFIG_ATA_ACPI case in libata.h.

If a USB controller with XHCI_RESET_ON_RESUME goes to runtime suspend, a reset will be performed upon runtime resume. Any previously suspended devices attached to the controller will be re-enumerated at this time. This will cause problems, for example, if an open system call on the device triggered the resume (the open call will fail). Note that this change is only relevant when persist_enabled is not set for USB devices.

snd_soc_dapm_auto_nc_codec_pins() Call snd_soc_dapm_new_widgets() before the auto non-connected pins have been marked as not connected will power the system under the assumption that those pins are connected. Once the pins have been marked as disconnected the system there will be an additional power run. This can cause unnecessary power transitions. Calling snd_soc_dapm_new_widgets() only after the pins have been marked as non-connected avoids this.

Doing this multiple times before the card is fully initialized and all widgets have been added can cause unnecessary and even invalid power state transitions which can result in extra register writes and and also might cause clicks and pops.
