| | | | | | | | | | | | | | | | | | | | Enhancements to the WM8994 audio driver and new features on more modern devices in the series mean that we can no longer rely on VMID being active as an indication that the device is active.

| | | | | | | | | | | | | | | | | | I was trying to fix the error handling part because in the case of request_irq failure, it should call kthread_stop instead of free_irq.

* | mfd: Rename wm8350 static gpio_set_debounce()Sascha Hauer2011-09-06
|/ | | | | | | | | | | | | | | The kernel already has a function with this name declared in asm-generic/gpio.h. So if this header leaks into wm8350/gpio.c we get drivers/mfd/wm8350-gpio.c:40:12: error: conflicting types for 'gpio_set_debounce' include/asm-generic/gpio.h:156:12: note: previous declaration of 'gpio_set_debounce' was here Fix this by adding a wm8350_ prefix to the function.

* mfd: Fix mismatch in twl4030 mutex lock-unlockSanjeev Premi2011-07-31
| | | | | | | | | | | | | A mutex is locked on entry into twl4030_madc_conversion(). Immediate return on some error conditions leaves the mutex locked. This patch ensures that mutex is always unlocked before leaving the function.

* mfd: Fix the omap-usb-host clock API usage on usbhs_disable()Keshava Munegowda2011-07-31
| | | | | | | | | | | | usbhs_disable function was invoking clk_enable() instead of clk_disable(), thus only increasing the clock usage counter and preventing this particular clock from being ever turned off. Because of this, the power domain of omap4 the USB Host subsystem would never reach lower power states.This patch calls clk_disable() in usbhs_disable function Signed-off-by: Keshava Munegowda <keshava_mgowda@ti.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

* mfd: Avoid two assignments if failures happen in tps65910_i2c_probeJesper Juhl2011-07-31
| | | | | | | | | | | | | | | | In drivers/mfd/tps65910.c:tps65910_i2c_probe() there's potential for a tiny optimization. We assign to init_data->irq and init_data->irq_base long before we need them, and there are two potential exits from the function before they are needed. Moving the assignments below these two potential exits means we completely avoid doing them in these two (failure) cases.
