gpiolib: Don't return -EPROBE_DEFER to sysfs, or for invalid gpios

2012-11-05T08:56:48Z

commit ad2fab36d7922401c4576fb7ea9b21a47a29a17f upstream. gpios requested with invalid numbers, or gpios requested from userspace via sysfs should not try to be deferred on failure. Signed-off-by: Mathias Nyman Signed-off-by: Linus Walleij Signed-off-by: Greg Kroah-Hartman

gpio-timberdale: fix a potential wrapping issue

2012-11-05T08:56:48Z

commit d79550a7bc35c16476ebdc27c78378d8093390ec upstream. ->last_ier is an unsigned long but the high bits can't be used int the original code because the shift wraps. Signed-off-by: Dan Carpenter Signed-off-by: Linus Walleij Signed-off-by: Greg Kroah-Hartman

gpio-lpc32xx: Fix value handling of gpio_direction_output()

2012-09-24T19:56:01Z

For GPIOs of gpio-lpc32xx, gpio_direction_output() ignores the value argument (initial value of output). This patch fixes this by setting the level accordingly. Cc: stable@kernel.org Signed-off-by: Roland Stigge Acked-by: Alexandre Pereira da Silva Signed-off-by: Linus Walleij

GPIO: gpio-pxa: fix building without CONFIG_OF

2012-08-14T04:50:36Z

Commit 7212157267 ("GPIO: gpio-pxa: fix devicetree functions") added an "xlate" function pointer to the irq_domain_ops, but this function is nor declared or defined anywhere when CONFIG_OF is disabled, causing the build error: drivers/gpio/gpio-pxa.c:532:11: error: 'irq_domain_xlate_twocell' undeclared here (not in a function) Extending the DT-only code section to cover the irq_domain_ops and the pxa_gpio_dt_ids solves this problem and makes it clearer which code is actually used without DT.

gpio: em: do not discard em_gio_irq_domain_cleanup

2012-08-10T10:27:46Z

The newly added gpio-em driver marks its em_gio_irq_domain_cleanup function as __devexit, which would lead to that function being discarded in case CONFIG_HOTPLUG is disabled. However, the function is also called by the error handling logic em_gio_probe, which would cause a jump into a NULL pointer if it was removed from the kernel or module. Without this patch, building kzm9d_defconfig results in: WARNING: drivers/gpio/built-in.o(.devinit.text+0x330): Section mismatch in reference from the function em_gio_probe() to the function .devexit.text:em_gio_irq_domain_cleanup() The function __devinit em_gio_probe() references a function __devexit em_gio_irq_domain_cleanup(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __devexit annotation of em_gio_irq_domain_cleanup() so it may be used outside an exit section.
