2010-09-14HID: fix hiddev's use of usb_find_interfaceGuillaume Chazarain
My macbook infrared remote control was broken by commit bd25f4dd6972755579d0ea50d1a5ace2e9b00d1a ("HID: hiddev: use usb_find_interface, get rid of BKL"). This device appears in dmesg as: apple 0003:05AC:8242.0001: hiddev0,hidraw0: USB HID v1.11 Device [Apple Computer, Inc. IR Receiver] on usb-0000:00:1d.2-1/input0 It stopped working as lircd was getting ENODEV when opening /dev/usb/hiddev0. AFAICS hiddev_driver is a dummy driver so usb_find_interface(&hiddev_driver) does not find anything.

2010-08-16USB HID: Add ID for eGalax Multitouch used in JooJoo tabletChris Ball
The JooJoo tablet (http://thejoojoo.com/) contains an "eGalax Inc. USB TouchController", and this patch hooks it up to the egalax-touch driver. Without the patch we don't get any cursor motion, since it comes through Z/RX rather than X/Y. (The egalax-touch driver does not yet generate a correct event sequence for the "serial" protocol used by this device, though -- see the note added to the code, which comes from research by Stéphane Chatty.)

2010-08-13HID: hiddev: fix memory corruption due to invalid intfdataJiri Kosina
Commit bd25f4dd6972755579d0 ("HID: hiddev: use usb_find_interface, get rid of BKL") introduced using of private intfdata in hiddev for purpose of storing hiddev pointer. This is a problem, because intf pointer is already being set to struct hid_device pointer by HID core. This obviously lead to memory corruptions at device disconnect time, such as WARNING: at lib/kobject.c:595 kobject_put+0x37/0x4b() kobject: '(null)' (ffff88011e9cd898): is not initialized, yet kobject_put() is being called. Convert hiddev into accessing hiddev through struct hid_device which is in intfdata already.

2010-08-13HID: hiddev: protect against disconnect/NULL-dereference raceChris Ball
One of our users reports consistently hitting a NULL dereference that resolves to the "hid_to_usb_dev(hid);" call in hiddev_ioctl(), when disconnecting a Lego WeDo USB HID device from an OLPC XO running Scratch software. There's a FIXME comment and a guard against the dereference, but that happens farther down the function than the initial dereference does. This patch moves the call to be below the guard, and the user reports that it fixes the problem for him.

2010-07-13HID: hiddev: use usb_find_interface, get rid of BKLArnd Bergmann
This removes the private hiddev_table in the usbhid driver and changes it to use usb_find_interface instead. The advantage is that we can avoid the race between usb_register_dev and usb_open and no longer need the big kernel lock. This doesn't introduce race condition -- the intf pointer could be invalidated only in hiddev_disconnect() through usb_deregister_dev(), but that will block on minor_rwsem and not actually remove the device until usb_open().

2010-07-12HID: picolcd: implement refcounting of framebufferBruno Prémont
As our device may be hot-unplugged and framebuffer cannot handle this case by itself we need to keep track of usage count so as to release fb_info and framebuffer memory only after the last user has closed framebuffer. We need to do the freeing in a scheduled work as fb_release() is called with fb_info lock held. Signed-off-by: Bruno Prémont <bonbons@linux-vserver.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2010-07-12HID: picolcd: do not reallocate memory on depth changeBruno Prémont
Reallocating memory in depth change does not work well if some userspace application has mmapped() the framebuffer as that mapping does not get adjusted (thus application continues to write to old buffer). In addition doing deferred_io_cleanup() and init() inside of set_par() tends to deadlock with fbcon's flashing cursor. Avoid all this by allocating a buffer that can hold 8bpp framebuffer and just use 1/8 of it while running at 1bpp. Signed-off-by: Bruno Prémont <bonbons@linux-vserver.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
