2011-05-26drivers/char/ppdev.c: put gotten port valueJulia Lawall
parport_find_number() calls parport_get_port() on its result, so there should be a corresponding call to parport_put_port() before dropping the reference. Similar code is found in the function register_device() in the same file. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @exists@ local idexpression struct parport * x; expression ra,rr; statement S1,S2; @@ x = parport_find_number(...) ... when != x = rr when any when != parport_put_port(x,...) when != if (...) { ... parport_put_port(x,...) ...} ( if(<+...x...+>) S1 else S2 | if(...) { ... when != x = ra when forall when != parport_put_port(x,...) *return...; } ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-05-26kgdbts: unify/generalize gdb breakpoint adjustmentMike Frysinger
The Blackfin arch, like the x86 arch, needs to adjust the PC manually after a breakpoint is hit as normally this is handled by the remote gdb. However, rather than starting another arch ifdef mess, create a common GDB_ADJUSTS_BREAK_OFFSET define for any arch to opt-in via their kgdb.h.

2011-05-26mfd: Fix tps6586x GPIO value settingVincent Palatin
In the current code, every time we set a TPS6586x GPIO pin, the tps6586x_gpio_set function is resetting all other GPIO pins. We need to update the right GPIOxOUT bit of the GPIOSET2 register instead of overriding the full value. Tested by setting sequentially GPIO2 and GPIO3 and verifying the pins voltage.

2011-05-26mfd: Add pm8xxx irq supportAbhijeet Dharmapurikar
Add support for the irq controller in Qualcomm 8xxx pmic. The 8xxx interrupt controller provides control for gpio and mpp configured as interrupts in addition to other subdevice interrupts. The interrupt controller also provides a way to read the real time status of an interrupt. This real time status is the only way one can get the input values of gpio and mpp lines.
