usb: gadget: multi: convert to new interface of f_mass_storage

2013-10-10T15:24:49+00:00

Convert the legacy multi gadget to the new interface of f_mass_storage,
so that later the compatibility layer in f_mass_storage can be removed.

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

2013-10-10T15:24:04+00:00

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.

usb: gadget: create a utility module for mass_storage

2013-10-01T14:50:57+00:00

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()

2013-09-17T15:59:19+00:00

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.
  This is often because .LM2953 lacks a __init
  annotation or the annotation of _cdc_do_config is wrong.

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

2013-07-29T11:15:18+00:00

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_*).
