This is done as simple code transformation, the semantics of the IRQ API provided by the core are are still very different to those of genirq (mainly with regard to masking). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

Abusing subdev drvdata is not needed anymore, as all pcap subdevs are now retrieving the pcap pointer from their parent device. This change removes a leftover coming from early versions of ezx-pcap and its subdevs drivers.

Add function to allow the configuation fo the VDCDC2 register by external users, to allow changing of the standard and low-power running modes. This is needed, for example, for the Simtec IM2440D20 where we need to use the low-power mode to shutdown the LDO/DCDC that are not needed during suspend (saving substantial power) and the runtime use of the low-power mode to change VCore.

If the board does not care where the TPS turns up, then specifiying the value -1 to get gpiolib to dynamically allocate the base for the chip is valid. Change the test to look for != 0, so that any boards specifying zero will not end up with gpio that they didn't want.

Based on Aaro's previous fix, this needs to be fixed for the newly added remap_off and remap_sleep resources as well. The code tries to skip values initialized with -1, but since the values are unsigned the comparison is always true. The patch eliminates the following compiler warnings: drivers/mfd/twl4030-power.c: In function 'twl4030_configure_resource': drivers/mfd/twl4030-power.c:338: warning: comparison is always true due to limited range of data type Signed-off-by: Amit Kucheria <amit.kucheria@verdurent.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

Currently the pcf50633-regulator driver data is set to the pcf50633 core structure, but the pcf50633-regulator remove handler assumes that it is set to the regulator device. This patch fixes the issue by accessing the pcf506533 core structure through its parent device and setting the driver data to the regulator device.

Lars-Peter Clausen authored
Since platform_device_add_data copies the passed data, the allocated subdev_pdata is never freed. A simple fix would be to either free subdev_pdata or put it onto the stack. But since the pcf50633 child devices can rely on beeing children of the pcf50633 core device it's much more elegant to get access to pcf50633 core structure through that link. This allows to get completly rid of pcf5033_subdev_pdata.

Rather than open coding individual IRQs in each function which manipulates them store data for IRQs in a table which is then referenced in the users. This is a substantial code shrink and should be a performance win in cases where only a single IRQ goes off at once since instead of reading four of the second level IRQ registers for each interrupt we read only the sub-registers which have had an interrupt flagged.

In preparation for refactoring - it's over 700 lines of well-isolated code and having it in a file by itself makes things more managable.

Linus Torvalds authored
As shown by the previous patch (6698e347: "tty: Fix BKL taken under a spinlock bug introduced in the BKL split") the BKL removal is prone to some subtle issues, where removing the BKL in one place may in fact make a previously nested BKL call the new outer call, and then prone to nasty deadlocks with other spinlocks. In general, we should never take the BKL while we're holding a spinlock, so let's just add a "might_sleep()" to it (even though the BKL doesn't technically sleep - at least not yet), and we'll get nice warnings the next time this kind of problem happens during BKL removal.

The fasync path takes the BKL (it probably doesn't need to in fact) while holding the file_list spinlock. You can't do that with the kernel lock: it causes lock inversions and deadlocks. Leave the BKL over that bit for the moment. Identified by AKPM.
