2007-07-16backlight: Convert from struct class_device to struct deviceRichard Purdie1-2/+2
Convert the backlight and LCD classes from struct class_device to struct device since class_device is scheduled for removal. One nasty API break is the backlight power attribute has had to be renamed to bl_power and the LCD power attribute has had to be renamed to lcd_power since the original names clash with the core. I can't see a way around this. Signed-off-by: Richard Purdie <[email protected]> Acked-by: Greg Kroah-Hartman <[email protected]>
2007-07-12USB: Support Blackberry Pearl with berry_chargeJeremy Katz1-0/+35
The Blackberry Pearl (8100) needs similar tweaks as older Blackberry models to be able to charge when connected via USB. The Pearl also adds an additional need to go into a separate mode for fully accessing the device; do that by default as well.

2007-07-12USB: prevent char device open/deregister raceAlan Stern10-198/+62
This patch (as908) adds central protection in usbcore for the prototypical race between opening and unregistering a char device. The spinlock used to protect the minor-numbers array is replaced with an rwsem, which can remain locked across a call to a driver's open() method. This guarantees that open() and deregister() will be mutually exclusive. The private locks currently used in several individual drivers for this purpose are no longer necessary, and the patch removes them. The following USB drivers are affected: usblcd, idmouse, auerswald, legousbtower, sisusbvga/sisusb, ldusb, adutux, iowarrior, and usb-skeleton. As a side effect of this change, usb_deregister_dev() must not be called while holding a lock that is acquired by open(). Unfortunately a number of drivers do this, but luckily the solution is simple: call usb_deregister_dev() before acquiring the lock. In addition to these changes (and their consequent code simplifications), the patch fixes a use-after-free bug in adutux and a race between open() and release() in iowarrior.

2007-07-06potential compiler error, irqfunc caller sites updateYoann Padioleau1-1/+1
In 7d12e780e003f93433d49ce78cfedf4b4c52adc5 David Howells performed this evolution: "IRQ: Maintain regs pointer globally rather than passing to IRQ handlers" He correctly updated many of the function definitions that were using this extra regs pointer parameter but forgot to update some caller sites of those functions. The reason the modifications was not properly done on all drivers is that some drivers were rarely compiled because they are for AMIGA, or that some code sites were inside #ifdefs where the option is not set or inside #if 0. Here is the semantic patch that found the occurences and fixed the problem. @ rule1 @ identifier fn; identifier irq, dev_id; typedef irqreturn_t; @@ static irqreturn_t fn(int irq, void *dev_id) { ... } @@ identifier rule1.fn; expression E1, E2, E3; @@ fn(E1, E2 - ,E3 ) Signed-off-by: Yoann Padioleau <[email protected]> Cc: "David S.

2007-06-25USB: usblcd doesn't limit memory consumption during writeOliver Neukum1-4/+18
usblcd currently has no way to limit memory consumption by fast writers. This is a security problem, as it allows users with write access to this device to drive the system into oom despite resource limits. Here's the fix taken from the modern skeleton driver.

2007-04-27USB: iowarrior.c: timeouts too small in usb_control_msg callsEberhard Fahle1-8/+6
The driver uses usb_control_msg() for exchanging data with the device. When the driver lived freeley _outside_ the kernel tree (pre 2.6.21) the timeouts for these calls where set to 5*HZ for reading, 1HZ for writing. (These timeouts seemed to work fine for all users of the driver, at least nobody complained in the last 2 years. The current code (2.6.21-rc5) removed the 'HZ' from the timeouts and left the driver with 5 jiffies for reading and 1 jiffy for writing. My new machine is fast, but not that fast. The patch also removes a useless debug statement, which was left over from testing a broken firmware version From: Eberhard Fahle <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

2007-02-20backlight: Separate backlight properties from backlight ops pointersRichard Purdie1-5/+6

2007-02-20backlight: Fix external uses of backlight internal semaphoreRichard Purdie1-6/+0
backlight_device->sem has a very specific use as documented in the header file. The external users of this are using it for a different reason, to serialise access to the update_status() method. backlight users were supposed to implement their own internal serialisation of update_status() if needed but everyone is doing things differently and incorrectly. Therefore add a global mutex to take care of serialisation for everyone, once and for all. Locking for get_brightness remains optional since most users don't need it. Also update the lcd class in a similar way. Signed-off-by: Richard Purdie <[email protected]>
