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_*).

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

2013-06-10T14:58:08+00:00

Converting rndis to the new function interface requires converting
the USB rndis' function code and its users.

This patch converts the f_rndis.c to the new function interface.

The file is now compiled into a separate usb_f_rndis.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: f_ecm: convert to new function interface with backward compatibility

2013-06-10T14:16:02+00:00

Converting ecm to the new function interface requires converting
the USB ecm's function code and its users.

This patch converts the f_ecm.c to the new function interface.

The file is now compiled into a separate usb_f_ecm.ko module.

usb: gadget: rndis: convert into module

2013-06-10T14:11:33+00:00

In order to convert to configfs the usb functions need to be converted
to a new interface and compiled as modules. This patch creates an rndis
module which will be used by the new functions. After all users of
f_rndis are converted to the new interface, this module can be
merged with f_rndis module.

usb: gadget: u_ether: convert into module

2013-06-10T14:10:57+00:00

u_ether.c has been #include'd by all gadgets which implement
USB Ethernet functions. In order to add configfs support,
the f_ecm.c, f_eem.c, f_ncm.c, f_subset.c, f_rndis.c need to be
converted into modules and must not be #include'd. Consequently,
the u_ether.c needs to be a module too, in a manner similar
to u_serial.c. The resulting module should not take any parameters,
so they are pushed to the current users of it, that is ether.c,
g_ffs.c, multi.c, ncm.c, nokia.c.

usb: gadget: push tty port allocation from gadget into f_acm

2013-04-03T11:43:31+00:00

It possible to allocate the tty port number within the "instance"
structure of the function and there is no need to expose this
information within the gadget and therefore it is removed here.
This patch converts only f_acm and all its users. The other gadgets will
follow once the function is converted to the function interface.

usb: gadget: move the global the_dev variable to their users

2013-04-03T11:43:31+00:00

the u_ether.c file has a global variable named the_dev which keeps a
pointer to the network device after it has been created via
gether_setup_name(). It is only used internally by u_ether. This patches
moves the variable to its users and passes it via the port.ioport where
it is saved later anyway.
