The genirq implementation does not allow modules to implement irq_chips so the conversion of WM8350 to genirq means we can no longer allow the driver to be built as a module. Signed-off-by:

This gives us use of the diagnostic facilities genirq provides and will allow implementation of interrupt support for the WM8350 GPIOs. Stub functions are provided to ease the transition of the individual drivers, probably after additional work to pass the IRQ numbers via the struct devices. Signed-off-by:

Unlike the wm8350-custom code genirq nests enable and disable calls so we can't just unconditionally mask or unmask the interrupt, we need to remember the state we set and only mask or unmask when there is a real change. Signed-off-by:

The structure t7l66xb should not be freed before the subsequent references to its fields in the arguments to clk_put. Furthermore, this structure is allocated near the beginning of the function, and a goto to the label err_noirq appears after a successful allocation, so it would seem that the kfree should be moved down below this label. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,e; identifier f; iterator I; statement S; @@ *kfree(x); ... when != &x when != x = e when != I(x,...) S *x->f // </smpl> Signed-off-by:

This reverts commit a069c266. It turns ou that not only was it missing a case (XFS) that needed it, but perhaps more importantly, people sometimes want to enable new modules that they hadn't had enabled before, and if such a module uses list_sort(), it can't easily be inserted any more. So rather than add a "select LIST_SORT" to the XFS case, just leave it compiled in. It's not all _that_ big, after all, and the inconvenience isn't worth it. Requested-by:

This adds separate I/O and memory specs, so we don't have to change the field width in a shared spec, which then lets us make all the specs const and static, since they never change. Signed-off-by:

Reducing the size of struct printf_spec is a good thing because multiple instances are commonly passed on stack. It's possible for type to be u8 and field_width to be s8, but this is likely small enough for now. Signed-off-by:

The caller of usbfs_conn_disc_event() in some cases (but not always) already holds usbfs_mutex, so trying to protect the event counter with that lock causes nasty deadlocks. The problem was introduced by commit 554f7696 ("USB: Remove BKL from poll()") when the BLK protection was turned into using the mutex instead. So fix this by using an atomic variable instead. And while we're at it, get rid of the atrocious naming of said variable and the waitqueue it is associated with. This also cleans up the unnecessary locking in the poll routine, since the whole point of how the pollwait table works is that you can just add yourself to the waiting list, and then check the condition you're waiting for afterwards - avoiding all races. It also gets rid of the unnecessary dynamic allocation of the device status that just contained a single word. We should use f_version for this, as Dmitry Torokhov points out. That simplifies everything further. Reported-and-tested-by:

The cs5535-gpio driver's get() function was returning the output value. This means that the GPIO pins would never work as an input, even if configured as an input. The driver should return the READ_BACK value, which is the sensed line value. To make that work when the direction is 'output', INPUT_ENABLE needs to be set. In addition, the driver was not disabling OUTPUT_ENABLE when the direction is set to 'input'. That would cause the GPIO to continue to drive the pin if the direction was ever set to output. This issue was noticed when attempting to use the gpiolib driver to read an external input. I had previously been using the char/cs5535-gpio driver. Signed-off-by:
