d537155a09 Input: adp5588-keys - use more obvious i2c_device_id name string
KBUILD_MODNAME normalizes "-" to "_".  This is non-obvious and results in
the id name for ADP5588 being "adp5588_keys" while the other supported id
is "adp5587-keys".  So avoid this define and use an explicit string as the
id name.

2991a1ca6e Input: ads7846 - switch to using threaded IRQ
Commit 9114337 introduces regulator operations in ads7846 touchscreen
driver. Among these operations, some are called while holding a
spinlock. On many platforms regulators reside on slow buses, such as
I2C/SPI and require sleep while accessing them.

The touchscreen itself is also a SPI device and currently relies on
asynchronous SPI access to avoid sleeping in interrupt context. Let's
switch to using threaded IRQ to be able to access SPI bus
synchronously (which simplifies driver a bit); it also allows safe
access to the regulators as well.

This has been tested on the ti_omap3530evm board:
 1) using ts_lib after normal boot
 2) using ts_lib after "#echo 1/0 > /sys/bus/spi/devices/spi0.1/disable"
 3) using ts_lib after "#echo mem > /sys/power/state" and "wake up"

Also tested on pandora.

f6cd378372 Input: wacom - fix runtime PM related deadlock
When runtime PM is enabled by default for input devices, X hangs in
wacom open:
[<ffffffff814a00ea>] mutex_lock+0x1a/0x40
[<ffffffffa02bc94b>] wacom_resume+0x3b/0x90 [wacom]
[<ffffffff81327a32>] usb_resume_interface+0xd2/0x190
[<ffffffff81327b5d>] usb_resume_both+0x6d/0x110
[<ffffffff81327c24>] usb_runtime_resume+0x24/0x40

[<ffffffff8130a23a>] __pm_runtime_resume+0x1da/0x450
[<ffffffff8130a53a>] pm_runtime_resume+0x2a/0x50
[<ffffffff81328176>] usb_autopm_get_interface+0x26/0x60
[<ffffffffa02bc626>] wacom_open+0x36/0x90 [wacom]

wacom_open() takes wacom->lock and calls usb_autopm_get_interface(),
which in turn calls wacom_resume() which tries to acquire the lock
again.

The fix is to call usb_autopm_get_interface() first, before we take
the lock.

Since we do not do usb_autopm_put_interface() until wacom_close()
is called runtime PM is effectively disabled for the driver, however
changing it now would risk regressions so the complete fix will
have to wait till the next merge window.
