usb: gadget: Gadget directory cleanup - group legacy gadgets

2014-07-16T17:14:05Z

The drivers/usb/gadget directory contains many files. Files which are related can be distributed into separate directories. This patch moves the legacy gadgets (i.e. those not using configfs) into a separate directory. Signed-off-by: Andrzej Pietrasiewicz Signed-off-by: Felipe Balbi

usb: gadget: Convert drivers to use module_usb_composite_driver()

2014-07-10T13:37:09Z

Use the module_usb_composite_driver() macro where applicable to eliminate the module_init/module_exit boilerplate in USB gadget composite drivers. Signed-off-by: Tobias Klauser Signed-off-by: Felipe Balbi

USB: gadget: fix up some comments about CONFIG_USB_DEBUG

2013-12-22T00:01:00Z

These two gadget drivers said that their #endif was for CONFIG_USB_DEBUG, but they really were not, so fix them up to be correct. Cc: Felipe Balbi Signed-off-by: Greg Kroah-Hartman

usb: gadget: f_mass_storage: convert to new function interface with backward compatibility

2013-10-10T15:24:04Z

Converting mass storage to the new function interface requires converting the USB mass storage's function code and its users. This patch converts the f_mass_storage.c to the new function interface. The file is now compiled into a separate usb_f_mass_storage.ko module. The old function interface is provided by means of a preprocessor conditional directives. After all users are converted, the old interface can be removed. Signed-off-by: Andrzej Pietrasiewicz Signed-off-by: Kyungmin Park Acked-by: Michal Nazarewicz Signed-off-by: Felipe Balbi

usb: gadget: create a utility module for mass_storage

2013-10-01T14:50:57Z

Converting to configfs requires making the f_mass_storage.c a module. But first we need to get rid of "#include "storage_common.c". This patch makes storage_common.c a separately compiled file, which is built as a utility module named u_ms.ko. After all mass storage users are converted to the new function interface this module can be eliminated by merging it with the mass storage function's module. USB descriptors are exported so that they can be accessed from f_mass_storage. FSG_VENDOR_ID and FSG_PRODUCT_ID are moved to their only user. Handling of CONFIG_USB_GADGET_DEBUG_FILES is moved to f_mass_storage.c. The fsg_num_buffers static is moved to FSG_MODULE_PARAMETER users, so instead of using a global variable the f_mass_storage introduces fsg_num_buffers member in fsg_common (and fsg_config). fsg_strings and fsg_stringtab are moved to f_mass_storage.c.

usb: gadget: add '__ref' for rndis_config_register() and cdc_config_register()

2013-09-17T15:59:19Z

They are only called by '__ref' function multi_bind(), and they will call '__init' functions, so recommend to let them '__ref' too. The related warnings: WARNING: drivers/usb/gadget/g_multi.o(.text+0xded6): Section mismatch in reference from the variable .LM2921 to the variable .init.text:_rndis_do_config The function .LM2921() references the variable __init _rndis_do_config. This is often because .LM2921 lacks a __init annotation or the annotation of _rndis_do_config is wrong. WARNING: drivers/usb/gadget/g_multi.o(.text+0xdf16): Section mismatch in reference from the variable .LM2953 to the variable .init.text:_cdc_do_config The function .LM2953() references the variable __init _cdc_do_config.

usb: gadget: multi: fix error return code in cdc_do_config()

2013-07-29T11:15:18Z

Fix to return a negative error code from the error handling case instead of 0, as returned elsewhere in this function. Introduced by commit 59835a (usb: gadget: multi: use function framework for ACM.) Make rndis_do_config() consistent with cdc_do_config() in the way it handles returning the PTR_ERR(f_acm_*).
