Add check if palette register number is in correct range for few drivers which miss it. The regno value comes indirectly from user space. Two drivers has converted check from BUG_ON() macro to just return an error (non-zero value). Signed-off-by:

Drivers may use gpiolib sysfs as part of their public user space interface. The GPIO number and polarity might change from board to board. The gpio_export_link() call can be used to hide the GPIO number from user space. Add support for also hiding the GPIO line polarity changes from user space. Signed-off-by:

The rtc-omap driver currently assumes that the rtc's registers are at a fixed address and already mapped into virtual memory space. Remove those assumptions so the same driver can be used for similar devices that reside at different physical addresses (e.g., TI's DA8xx/OMAP-L13x SoC's). Also allow the possibility for the timer and alarm interrupts to use the same IRQ. Signed-off-by:

Add setting and clearing of the "pending" flag of the RTC alarm. The semantics follow the UEFI specification 2.2 available at http://www.uefi.org/specs/, i.e., the "pending" flag is cleared by disabling the alarm, but not by any other condition (such as the passing of time, a successful wakeup, or setting of a new alarm.)

Now that we've removed the BKL here, let's explicitly set llseek to no_llseek since the default llseek is not used here. The default_llseek function still contains the BKL. When we are auditing code to see if we can remove the BKL, this is one of the hidden considerations we need to take into account. i.e., is there syncronization between code that has the BKL and llseek. At the same time we remove the BKL it would be a good idea to do indicate when no llseek function is required, so we don't have to revisit this code again, when we are trying to determine if we can remove the BKL from the default_llseek.

- Call dev_set_drvdata before rtc device creation. - Use its own spinlock instead of rtc->irq_lock. Because pdata->rtc must be initialized to use the irq_lock (pdata->rtc->irq_lock). There is a small window which rtc methods can be called before pdata->rtc is initialized. And there is no need use the irq_lock to protect hardware registers. The driver's own spinlock shoule be enough. - Check pdata->rtc before calling rtc_update_irq. - Use alarm_irq_enable and remove ioctl routine. - Use devres APIs and simplify error/remove path. These fixes are ported from ds1553 driver and just compile-tested only. Signed-off-by:

I noticed that rtc wont generate interrupts after a resume from disk. Here hpet rtc emulation is used. Problem is that rtc hpet comparator, isn't reinitialized after resume. Easiest way to solve this, is always mask all hpet interrupts on suspend This is triggered, when suspending with alarm set. Otherwise, hpet driver will think it doesn't need to reinitialize the rtc comparator, thus rtc interrupts won't work. This emulation isn't need for wakealarm. Signed-off-by:

We need to be able to cope with the directory mutex being held during ->d_revalidate() in some cases, but not all cases, and not necessarily by us. Because we need to release the mutex when we call back to the daemon to do perform a mount we must be sure that it is us who holds the mutex so we must redirect mount requests to ->lookup() if the mutex is held.

We unhash the dentry (in a subsequent patch) in ->d_revalidate() in order to send mount requests to ->lookup(). But then we can not rely on d_unhased() to give reliable results because it may be called at any time by any code path. The d_unhashed() function is used by __simple_empty() in the path walking callbacks but autofs mount point dentrys should have no directories at all so a list_empty() on d_subdirs should be (and is) sufficient.

The lookup functions for active and expiring dentrys use parameters that can be easily obtained on entry so we change the call to to take just the dentry. This makes the subsequent change, to send all lookups to ->lookup(), a bit cleaner. Signed-off-by:
