>commit 4a9bee8256a2dec26290a3bfff86ab86b8992547 >Author: Alan Stern <stern@rowland.harvard.edu> >Date: Tue Nov 6 15:01:52 2007 -0500 > > USB: uevent environment key fix > > This patch (as1010) was written by both Kay Sievers and me. It solves > the problem of duplicated keys in USB uevent structures by refactoring > the uevent subroutines, taking advantage of the way the hotplug core > calls uevent handlers for the device's bus and for the device's type. > Keys needed for both USB-device and USB-interface events are added in > usb_uevent(), which is the bus handler. Keys appropriate only for > USB-device or USB-interface events are added in usb_dev_uevent() or > usb_if_uevent() respectively, the type handlers. > > In addition, unnecessary tests for NULL pointers are removed as are > duplicated debugging log statements. > > Signed-off-by: Alan Stern <stern@rowland.harvard.edu> > Cc: Kay Sievers <kay.sievers@vrfy.org> > Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> > > > > > >commit ddc1fd6ac1f3ad3275e19451fb07d2eff249161c >Author: Alan Stern <stern@rowland.harvard.edu> >Date: Wed Nov 21 15:13:10 2007 -0800 > > USB HCD: avoid duplicate local_irq_disable() > > Arnd Bergmann wrote: > > usb_hcd_flush_endpoint() has a retry loop that starts with a spin_lock_irq(), > but only gives up the spinlock, not the irq_disable before jumping to the > rescan label. > > Alan Stern: > > I agree with your sentiment, but it would be better to solve this > problem without using local_irq_disable(). > > Signed-off-by: Alan Stern <stern@rowland.harvard.edu> > Cc: Arnd Bergmann <arnd@arndb.de> > Signed-off-by: Andrew Morton <akpm@linux-foundation.org> > Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> > > > > >commit 565227c08226e458da191518251dbff6831624c2 >Author: Benjamin Herrenschmidt <benh@kernel.crashing.org> >Date: Thu Dec 6 13:28:25 2007 -0800 > > usb: Remove broken optimisation in OHCI IRQ handler > > The OHCI IRQ handler has an optimisation that avoids reading some > chip registers when the controller reports that the interrupt was > triggered *only* because completed requests were written into the > controller's "done list" and handed to the host. > > This mechanism can't be used on some controllers. Among others, it > fails for the SA1111 and the AMCC 440EP PowerPC processor. > > This patch removes the optimisation and makes the code clearer. > > Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> > Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> > Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> > > > > >commit 4a56087f3b7660c9824e9ec69b96ccf8d9b25d1c >Author: Mauro Carvalho Chehab <mchehab@infradead.org> >Date: Tue Dec 11 14:59:10 2007 -0300 > > V4L/DVB (6794): Fix compilation when dib3000mc is compiled as a module > > As reported by Andrew Morton: > > > ERROR: "dibusb_dib3000mc_frontend_attach" [drivers/media/dvb/dvb-usb/dvb-usb-nova-t-usb2.ko] undefined! > > ERROR: "dibusb_dib3000mc_tuner_attach" [drivers/media/dvb/dvb-usb/dvb-usb-nova-t-usb2.ko] undefined! > > ERROR: "dibusb_dib3000mc_frontend_attach" [drivers/media/dvb/dvb-usb/dvb-usb-dibusb-mc.ko] undefined! > > ERROR: "dibusb_dib3000mc_tuner_attach" [drivers/media/dvb/dvb-usb/dvb-usb-dibusb-mc.ko] undefined! > > ERROR: "dibusb_dib3000mc_frontend_attach" [drivers/media/dvb/dvb-usb/dvb-usb-a800.ko] undefined! > > ERROR: "dibusb_dib3000mc_tuner_attach" [drivers/media/dvb/dvb-usb/dvb-usb-a800.ko] undefined > > Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
