2013-10-10usb: gadget: mass_storage: convert to new interface of f_mass_storageAndrzej Pietrasiewicz
Convert old mass_storage gadget to use the new interface of f_mass_storage so that later the compatibility layer in f_mass_storage can be removed. struct fsg_common is not known to mass_storage.c, so a setter method is added to f_mass_storage.

2013-10-10usb: gadget: f_mass_storage: convert to new function interface with backward ↵Andrzej Pietrasiewicz
compatibility 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.

2013-10-01usb: gadget: create a utility module for mass_storageAndrzej Pietrasiewicz
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.

2012-09-10usb: gadget: Provide a default implementation of default manufacturer stringSebastian Andrzej Siewior
Some gadgets provide custom entry here. Some may override it with an etntry that is also created by composite if there was no value sumbitted at all. This patch removes all "custom manufacturer" strings which are the same as these which are created by composite. Then it moves the creation of the default manufacturer string to usb_composite_overwrite_options() in case no command line argument has been used and the entry is still an empty string. By doing this we get rid of the global variable "composite_manufacturer" in composite.

2012-09-10usb: gadget: push all usb_composite_driver structs into __refdataSebastian Andrzej Siewior
As it turns out, Sam's comment was better than I initially assumed. This patch pushes as struct usb_composite_driver data structures into __refdata section to avoid a section missmatch report from modpost because the ->bind() can be marked __init. The only downside is that modpost does not check between ->bind() and other member. However, it is temporary.

2010-10-22USB: gadget: mass_storage: moved strings handling code to compositeMichal Nazarewicz
This patch removes string registration from the Mass Storage Gadget. With recent changes to the composite framework, all that we need is handled by the composite layer. This means composite registers a string ID for manufacturer and product. This also adds the "needs_serial" so that composite layer will issue a warning if user space fails to provide the iSerialNumber module parameter.

2010-08-10USB: gadget: f_mass_storage: added eject callbackMichal Nazarewicz
Added pre_eject() and post_eject() callbacks which are called before and after removable logical unit is ejected. The first can prevent logical unit from being ejected. This commit also changes the way callbacks are passed to the function from gadget. A fsg_operations structure has been created which lists all callbacks -- this is passed to the fsg_config. This is important because it changes the way thread_exits() callback is passed.

2010-03-02USB: mass_storage: eject LUNs on thread exitMichal Nazarewicz
Adds a fallback which forces all LUNs ejection (including non-removable and with prevent_medium_removal flag) when mass storage function (MSF) worker thread exits and gadget fails to handle the situation. Previously, if thread_exits was not specified mass storage function (MSF) did nothing when exiting thread as it's unclear for *function* what to do when it's thread terminates so responsibility of handling this situation was left to the *gadget* using the function. The g_mass_storage handled the situation by unregistering itself (the same thing that file storage gadget does). However, g_multi did nothing and so MSF did not eject LUNs which prevented file system unmounting.

2009-12-11USB: g_mass_storage: fsg_config added & module params handlig changedMichal Nazarewicz
Removed all references to mod_data in f_mass_storage.c and instead created fsg_config structure fsg_common_init() takes as an argument -- it stores all configuration options that were previously taken from mod_data. Moreover, The fsg_config structure allows per-LUN configuration of removable and CD-ROM emulation. Module parameters are handled by defining an object of fsg_module_parameters structure and then declaring module parameters via FSG_MODULE_PARAMETERS() macro. It adds proper declarations to the code making specified object be populated from module parameters. To use values stored there one may use either fsg_config_from_params() which will will a fsg_config structure with values taken from fsg_module_parameters structure or fsg_common_from_params() which will initialise fsg_common structure directly.
