rpmsg: char: Fix race between the release of rpmsg_eptdev and cdev
commit 7a534ae89e34e9b51acb5a63dd0f88308178b46a upstream.
struct rpmsg_eptdev contains a struct cdev. The current code frees
the rpmsg_eptdev struct in rpmsg_eptdev_destroy(), but the cdev is
a managed object, therefore its release is not predictable and the
rpmsg_eptdev could be freed before the cdev is entirely released.
The cdev_device_add/del() API was created to address this issue
(see commit '233ed09d7fda ("chardev: add helper function to register
char devs with a struct device")'), use it instead of cdev add/del().

rpmsg: char: Fix race between the release of rpmsg_ctrldev and cdev
commit b7fb2dad571d1e21173c06cef0bced77b323990a upstream.
struct rpmsg_ctrldev contains a struct cdev. The current code frees
the rpmsg_ctrldev struct in rpmsg_ctrldev_release_device(), but the
cdev is a managed object, therefore its release is not predictable
and the rpmsg_ctrldev could be freed before the cdev is entirely
released, as in the backtrace below.

bus: Make remove callback return void
The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

rpmsg: core: Add driver_data for rpmsg_device_id
Most device_id structs provide a driver_data field that can be used by drivers to associate data more easily for a particular device ID. Add the same for the rpmsg_device_id.

rpmsg: char: Return an error if device already open
The rpmsg_create_ept function is invoked when the device is opened. As only one endpoint must be created per device. It is not possible to open the same device twice. But there is nothing to prevent multi open. Return -EBUSY when device is already opened to have a generic error instead of relying on the back-end to potentially detect the error. Without this patch for instance the GLINK driver return -EBUSY while the virtio bus return -ENOSPC.

rpmsg: virtio: Register the rpmsg_char device
Instantiate the rpmsg_char device on virtio RPMsg bus creation. This provides the capability, with the RPMSG_CREATE_EPT_IOCTL ioctl, to create RPMsg char device endpoints relying on the rpmsg_chrdev_create_eptdev API. Notice that the created endpoints are attached to the rpmsg_ctldev device, but not associated to a channel. As consequence, the endpoint source and destination addresses have to been specified and there is no channel creation and no name service announcement to inform the remote side.

rpmsg: char: Use rpmsg_sendto to specify the message destination address
When the endpoint device is created by the application, a destination address is specified in the rpmsg_channel_info structure. Since the rpmsg_endpoint structure does not store the destination address, this destination address must be specified when sending a message. Replaces rpmsg_send with rpmsg_sendto to allow to specify the destination address. This implementation is requested for compatibly with some rpmsg backends like the virtio backend. For this, the GLINK an SMD drivers have been updated to support the rpmsg_sendto, even if the destination address is ignored for these backends. For these drivers, the rpmsg_send and rpmsg_trysend ops are preserved to avoid breaking the legacy.

ANDROID: rpmsg: core: Add signal API support
RPMSG unifies various transports that provide IPC to a remote proc.
Some of these transports require some set of side band signalling in
order to meet the specifications of the protocol they implement.
The GLINK native transport supports the tty serial signals to start
communication with modems that expect to receive the DTR serial signal.
Extend the rpmsg core with an interface to send and receive sideband
signals for the transports that need it.

rpmsg: Replace zero-length array with flexible-array
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.

compat_ioctl: move more drivers to compat_ptr_ioctl
The .ioctl and .compat_ioctl file operations have the same prototype so they can both point to the same function, which works great almost all the time when all the commands are compatible. One exception is the s390 architecture, where a compat pointer is only 31 bit wide, and converting it into a 64-bit pointer requires calling compat_ptr(). Most drivers here will never run in s390, but since we now have a generic helper for it, it's easy enough to use it consistently. I double-checked all these drivers to ensure that all ioctl arguments are used as pointers or are ignored, but are not interpreted as integer values.

rpmsg: glink: Free pending deferred work on remove
By just cancelling the deferred rx worker during GLINK instance teardown
any pending deferred commands are leaked, so free them.
