* power: gpio-charger: do not use gpio value directlyHeiko Stuebner2014-09-24
| | | | | | | | | | | Some gpio implementations return interesting values for gpio_get_value when the value is not 0 - as seen on a imx6sl board. Therefore do not use the value returned from gpio_get_value directly but simply check for 0 or not 0.

* power_supply: Don't iterate over devices to return -EPROBE_DEFERViresh Kumar2014-09-16
| | | | | | | | | | | This piece of code was added so that we return -EPROBE_DEFER when no devices are registered. But even if class_for_each_device() returns 0, we are going to return -EPROBE_DEFER only. And so this code isn't required at all. Remove it.

* power-supply: Avoid unnecessary 'goto' statementsViresh Kumar2014-09-16
| | | | | | | | | | | | Using 'goto' statements for freeing resources on failures is a good choice as it makes code very clean, and reduces the chances of human errors. Though in most cases compiler may take care of this. But adding unnecessary 'goto' statements wouldn't make anything better. Code becomes less readable actually.

* power-supply: Check for failures only when we can failViresh Kumar2014-09-16

| | | | | | | | | | | | | The 'if' statements in power_supply_changed_work() are mostly there for taking care of races and normally they will always evaluate to true.

| | | | | | | | | | | There is no need to check the value of ret.intval before returning it, as we will be returning zero explicitly when ret.intval is zero.

* power-supply: Don't return -EINVAL from __power_supply_find_supply_from_node()Viresh Kumar2014-09-16
| | | | | | | | | | | | | | | | | | We need to stop 'class_for_each_device' loop when a supply matches with the of-node. In order to achieve this we currently return -EINVAL from __power_supply_populate_supplied_from() on successful match. class_for_each_device() is free to return similar errors in other cases as well and so the choice of return value here isn't particularly great. This commit isn't removing the Hack but making it more elegant by returning '1' instead. Also power_supply_find_supply_from_node() can return errors other than -EPROBE_DEFER now if class_for_each_device() fails.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver was not bound checking the received length byte to ensure it was within the the buffer size that is allocated for SMBus blocks. This resulted in buffer overflows whenever an invalid length byte was received. It also failed to ensure the length byte was not zero. If it received zero, it would end up in an infinite loop as the at91_twi_read_next_byte function returned immediately without allowing RHR to be read to clear the RXRDY interrupt.

| * i2c: at91: Fix a race condition during signal handling in at91_do_twi_xfer.Simon Lindgren2014-09-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a race condition in at91_do_twi_xfer when signals arrive. If a signal is recieved while waiting for a transfer to complete wait_for_completion_interruptible_timeout() will return -ERESTARTSYS. This is not handled correctly resulting in interrupts still being enabled and a transfer being in flight when we return. Symptoms include a range of oopses and bus lockups. Oopses can happen when the transfer completes because the interrupt handler will corrupt the stack. If a new transfer is started before the interrupt fires the controller will start a new transfer in the middle of the old one, resulting in confused slaves and a locked bus. To avoid this, use wait_for_completion_io_timeout instead so that we don't have to deal with gracefully shutting down the transfer and disabling the interrupts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "clock-frequency" DT property is listed as optional, However, the current code stores the return value of of_property_read_u32 in the return code of mv64xxx_of_config, but then forgets to clear it after setting the default value of "clock-frequency". It is then passed out to the main probe function, resulting in a probe failure when "clock-frequency" is missing. This patch checks and then throws away the return value of of_property_read_u32, instead of storing it and having to clear it afterwards.

| * i2c: rcar: fix MNR interrupt handlingSergei Shtylyov2014-09-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes the MNR and MST interrupts happen simultaneously (stop automatically follows NACK, according to the manuals) and in such case the ID_NACK flag isn't set since the MST interrupt handling precedes MNR and all interrupts are cleared and disabled then, so that MNR interrupt is never noticed -- this causes NACK'ed transfers to be falsely reported as successful. Exchanging MNR and MST handlers fixes this issue, however the MNR bit somehow gets set again even after being explicitly cleared, so I decided to completely suppress handling of all disabled interrupts (which is a good thing anyway)...

Solve this by: - Also rename all the stub functions __gpiod_* - Moving the vararg hack outside of #ifdef CONFIG_GPIOLIB so these will always be available.
