| * | usb: musb: abstract out ULPI_BUSCONTROL register reads/writesMike Frysinger2010-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The USB PHY on current Blackfin processors is a UTMI+ level 2 PHY. However, it has no ULPI support - so there are no registers at all. That means accesses to ULPI_BUSCONTROL have to be abstracted away like other MUSB registers. This fixes building for Blackfin parts again.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EHCI driver stores in usb_host_endpoint.hcpriv a pointer to either an ehci_qh or an ehci_iso_stream structure, and uses the contents of the hw_info1 field to distinguish the two cases. After ehci_qh was split into hw and sw parts, ehci_iso_stream must also be adjusted so that it again looks like an ehci_qh structure. This fixes a NULL pointer access in ehci_endpoint_disable() when it tries to access qh->hw->hw_info1.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When isochronous URBs are shorter than one frame and when more than one ITD in a frame has been completed before the interrupt can be handled, scan_periodic() completes the URBs in the order in which they are found in the descriptor list. Therefore, the descriptor list must contain the ITDs in the correct order, i.e., a new ITD must be linked in after any previous ITDs of the same endpoint.

| * | USB: serial: use port endpoint size to determine if ep is availableJohan Hovold2010-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible to have a multi-port device with a port lacking an in or out bulk endpoint. Only checking for num_bulk_in or num_bulk_out is thus not sufficient to determine whether a specific port has an in or out bulk endpoint. This fixes potential null pointer dereferences in the generic open and write routines, as well as access to uninitialised fifo in write_room and chars_in_buffer. Also let write fail with ENODEV (instead of 0) on missing out endpoint (also on zero-length writes). Signed-off-by: Johan Hovold <jhovold@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* | | | usbfs: fix deadlock on 'usbfs_mutex', clean up pollLinus Torvalds2010-03-06

The problem was introduced by commit 554f76962d ("USB: Remove BKL from poll()") when the BLK protection was turned into using the mutex instead. So fix this by using an atomic variable instead. And while we're at it, get rid of the atrocious naming of said variable and the waitqueue it is associated with. This also cleans up the unnecessary locking in the poll routine, since the whole point of how the pollwait table works is that you can just add yourself to the waiting list, and then check the condition you're waiting for afterwards - avoiding all races. It also gets rid of the unnecessary dynamic allocation of the device status that just contained a single word. We should use f_version for this, as Dmitry Torokhov points out. That simplifies everything further.

But they only provide one which makes status or signal strength requests impossible while PPP is active. They also provide secondary USB interfaces that talk the Qualcomm Diagnostic Monitor (QCDM) protocol which can be used for status and strength. Make those QCDM ports accessible.

It uses the TIOCGSERIAL ioctl to determine if it's talking to a serial device or not, which I gather is rather common, but the pl2303 driver didn't implement that ioctl. Here's a patch, I'm not sure it's absolutely correct, I mostly looked at other similar usbserial drivers to see what I must do, but it works for me.
