2009-04-21drivers/input/serio/hp_sdc.c: fix crash when removing hp_sdc moduleHelge Deller
On parisc machines, which don't have HIL, removing the hp_sdc module panics the kernel. Fix this by returning early in hp_sdc_exit() if no HP SDC controller was found. Add functionality to probe for the hp_sdc_mlc kernel module (which takes care of the upper layer HIL functionality on parisc) after two seconds. This is needed to get all the other HIL drivers (keyboard / mouse/ ..) drivers automatically loaded by udev later as well.

2009-04-15Input: ads7846 - fix unsafe disable_irqBen Nizette
The use of disable_irq inside the handler for the interrupt being disabled has always been dangerous. disable_irq should wait for that handler to complete before returning -> deadlock. For some reason this wasn't actually the case until 3aa551c9b was merged but since this time, the ads7846 driver has deadlocked the system on first interrupt.

2009-04-02workqueue: add to_delayed_work() helper functionJean Delvare
It is a fairly common operation to have a pointer to a work and to need a pointer to the delayed work it is contained in.

2009-03-31proc 2/2: remove struct proc_dir_entry::ownerAlexey Dobriyan
Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it.

2009-03-16Rationalize fasync return valuesJonathan Corbet
Most fasync implementations do something like: return fasync_helper(...); But fasync_helper() will return a positive value at times - a feature used in at least one place. Thus, a number of other drivers do: err = fasync_helper(...); if (err < 0) return err; return 0; In the interests of consistency and more concise code, it makes sense to map positive return values onto zero where ->fasync() is called.

2009-03-09Input: add driver for S1 button of rb532Phil Sutter
Mikrotik's Routerboard 532 has two builtin buttons, from which one triggers a hardware reset. The other one is accessible through GPIO pin 1. Sadly, this pin is being multiplexed with UART0 input, so enabling it as interrupt source (as implied by the gpio-keys driver) is not possible unless UART0 has been turned off. The later one though is a rather bad idea as the Routerboard is an embedded device with only a single serial port, so it's almost always used as serial console device. This patch adds a driver based on INPUT_POLLDEV, which disables the UART and reconfigures GPIO pin 1 temporarily while reading the button state. This procedure works fine and has been tested as part of another, unpublished driver for this device. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
