* USB: ftdi_sio: isolate all device IDs to new ftdi_sio_ids.h headerAndreas Mohr2009-12-23
| | | | | | | | | | | | | | | | This is a strictly move-only patch to relocate all FTDI device product ID definitions to their own ftdi_sio_ids.h header (following the usual *_ids.h kernel tree convention, too), thus correcting the slightly too messy appearance (crucial driver defines were stuck somewhere in the decaying middle swamp of the huge existing header). Compile-tested, based on latest mainline git. Signed-off-by: Andreas Mohr <andi@lisas.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: emi62: fix crash when trying to load EMI 6|2 firmwareClemens Ladisch2009-12-23
| | | | | | | | | | | | | | | | | | | | | | | While converting emi62 to use request_firmware(), the driver was also changed to use the ihex helper functions. However, this broke the loading of the FPGA firmware because the code tries to access the addr field of the EOF record which works with a plain array that has an empty last record but not with the ihex helper functions where the end of the data is signaled with a NULL record pointer, resulting in: BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<f80d248c>] emi62_load_firmware+0x33c/0x740 [emi62] This can be fixed by changing the loop condition to test the return value of ihex_next_binrec() directly (like in emi26.c).

* USB: fix bugs in usb_(de)authorize_deviceAlan Stern2009-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1315) fixes some bugs in the USB core authorization code: usb_deauthorize_device() should deallocate the device strings instead of leaking them, and it should invoke usb_destroy_configuration() (which does proper reference counting) instead of freeing the config information directly. usb_authorize_device() shouldn't change the device strings until it knows that the authorization will succeed, and it should autosuspend the device at the end (having autoresumed the device at the start). Because the device strings can be changed, the sysfs routines to display the strings must protect the string pointers by locking the device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, if there was no firmware available, the DRM would just disable channel creation from userspace, but still use a single channel for its own purposes. With a bit of care it should actually be possible to do this, due to the DRM's very limited use of the engine. It currently doesn't work correctly however, resulting in corrupted fbcon and hangs on a number of cards. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

There's notes in nv40_grctx.c explaining most of the things we don't implement. If we discover if/why any of it is required further down the track, we'll handle it then. The PGRAPH state generated for each chipset should match what NVIDIA do almost exactly (there's a couple of exceptions). If someone has a lot of time on their hands, they could figure out the mapping of object/method to PGRAPH register and demagic the initial state a little, it's not terribly important however. At time of commit, confirmed to be working at least well enough for accelerated X (and where tested, for 3D apps) on NV40, NV43, NV44, NV46, NV49, NV4A, NV4B and NV4E. A module option has been added to force the use of external firmware blobs if it becomes required. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| * | drm: convert drm_ioctl to unlocked_ioctlArnd Bergmann2009-12-17

Moving the lock into the drm_ioctl function itself makes sure we blame the right subsystem and it gets us one step closer to eliminating the locked version of fops->ioctl. Since drm_ioctl does not require the lock itself, we only need to hold it while calling the specific handler. The 32 bit conversion handlers do not interact with any other code, so they don't need the BKL here either and can just call drm_ioctl. As a bonus, this cleans up all the other users of drm_ioctl which now no longer have to find the inode or call lock_kernel. [airlied: squashed the non-driver bits of the second patch in here, this provides the flag for drivers to use to select unlocked ioctls - but doesn't modify any drivers].
