2012-01-13module_param: make bool parameters really bool (drivers & misc)Rusty Russell
module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Acked-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-01-13module_param: check type correctness for module_param_arrayRusty Russell

2012-01-09misc: Remove max8997-muic sysfs attributesDonggeun Kim
The 'switch' sysfs attribute is used for showing and setting the switch state of the device. However, setting it from the userspace focibly is not appropriate. And showing the state can be handled from other places (e.g. external connector) in a unified manner. This patch removes the sysfs attribute. Plus, uevent messages for interrupts are also removed.

Concurrent access to UART2/combo-interface by multiple protocol drivers such as BT, FM and GPS caused issues during firmware download failure cases or cases when the firmware download took longer than usual. This was because of un-safe access to protos_registered & st_states. Protecting this will also make the registration complete callback un-safe for sleep.

Some devices need to know if the data is to be output or read, so add a data direction into the eeprom structure to tell the driver whether the data line should be driven. The user in this case is the Micrel KS8851 which has a direction control for the EEPROM data line and thus needs to know whether to drive it (writing) or to tristate it for receiving.

2011-11-15drivers/misc/eeprom: fix dependecy on 'PPC_MPC5200_GPIO'Paul Bolle
The driver for the DigsyMTC display configuration EEPROMs device got added by commit 469dded183 ("misc/eeprom: add eeprom access driver for digsy_mtc board"). Its Kconfig symbol depends on PPC_MPC5200_GPIO. But at the time that driver got added PPC_MPC5200_GPIO was already renamed to GPIO_MPC5200, by commit 6eae1ace68 ("gpio: Move mpc5200 gpio driver to drivers/gpio"). So make this driver depend on GPIO_MPC5200. And since GPIO_MPC5200 itself implies that GPIOLIB is set, that dependency can be dropped.

2011-10-31lis3lv02d: make regulator API usage unconditionalMark Brown
The regulator API contains a range of features for stubbing itself out when not in use and for transparently restricting the actual effect of regulator API calls where they can't be supported on a particular system so that drivers don't need to individually implement this. Simplify the driver slightly by making use of this idiom. The only in tree user is ecovec24 which does not use the regulator API.

The driver doesn't check the result and directly uses it as some sort of divisor in some places: msleep(lis3->pwron_delay / lis3lv02d_get_odr()); Under this circumstances, this could very well cause the "divide by zero" exception from above. For now, I fixed it the easiest and most obvious way: Check if the result is sane and if it isn't use a sane default instead. I went for "100" in the latter case, simply because /sys/devices/platform/lis3lv02d/rate returns it on a successful boot.
