2010-10-22usb gadget: don't save bind callback in struct usb_configurationUwe Kleine-König
The bind function is most of the time only called at init time so there is no need to save a pointer to it in the configuration structure. This fixes many section mismatches reported by modpost.

2010-10-22USB: Revert "USB: gadget: section mismatch warning fixed"Michal Nazarewicz
This reverts a commit which proposed an invalid solution for a section mismatch. Next 3 commits will fix it correctly. Conflicts: drivers/usb/gadget/mass_storage.c Signed-off-by: Michal Nazarewicz <m.nazarewicz@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
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: section mismatch warning fixedMichal Nazarewicz
In may gadgets bind and bind like functions were in a init section as they were only run during initialisation. However, being callback functions they were referenced from structures in “normal” sections. Changing the tag from “__init” to “__ref” fixes the warnings.

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.

2010-08-10USB: gadget: f_mass_storage: fsg_add() renamed to fsg_bind_config()Michal Nazarewicz
Mass Storage Function had a bit unique name for function used to add it to USB configuration. Renamed as to match naming convention of other functions.

2010-08-10USB: gadget: g_mass_storage: static data instead of dynamic allocationMichal Nazarewicz
This patch changes msg_do_config() function so that it uses a static object for a fsg_common structure instead of dynamically allocated. This is a micro-optimisation.

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: thread_exits callback addedMichal Nazarewicz
thread_exits callback has been added to fsg_common structure. This callback is called when MSF's thread exits (is terminated by a signal or function is unregistered). It's then gadget's responsibility to unregister the gadget. Signed-off-by: Michal Nazarewicz <m.nazarewicz@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

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.
