ADS7845 is a controller for 5-wire touch screens and somewhat different from 7846. It requires three serial communications to accomplish one complete conversion. Unlike 7846 it doesn't allow Z1-/Z2- position measurement. The patch extends the ads7846 driver to also support ads7845. The packet struct is extended to contain needed command and conversion buffers. ads7846_rx() and ads7846_rx_val() now differentiate between 7845 and 7846 case. ads7846_probe() is modified to setup ads7845 specific command and conversion messages and to switch ads7845 into power-down mode, since this is needed to be prepared to respond to pendown interrupts.

Some input events users such as Android require BTN_TOUCH events. Implement EV_KEY/BTN_TOUCH and make sure that the release event is not erroneous scheduled without a preceding valid touch. Avoid duplicated BTN_TOUCH events, even though input core filters them. Signed-off-by:

The ad7879 driver is using the old bus method of only supporting one at a time (I2C or SPI). So refactor it like the other input drivers that support multiple busses simultaneously. Signed-off-by:

gpiolib now has debounce support added in .35, so let's make use of it. This allows to use hardware GPIO debouncing on some platforms like OMAP. In case gpiolib debounce setup fails for some GPIO, the driver will fall back to timer based debouncing, which is what it used before. Signed-off-by:

A column or row configured as a GPI can be programmed to be part of the key event table and therefore also capable of generating a key event interrupt. A key event interrupt caused by a GPI follows the same process flow as a key event interrupt caused by a key press. GPIs configured as part of the key event table allow single key switches and other GPI interrupts to be monitored. As part of the event table, GPIs are represented by the decimal value 97 (0x61 or 1100001) through the decimal value 114 (0x72 or 1110010). See table below for GPI event number assignments for rows and columns. GPI Event Number Assignments for Rows Row0 Row1 Row2 Row3 Row4 Row5 Row6 Row7 97 98 99 100 101 102 103 104 GPI Event Number Assignments for Cols Col0 Col1 Col2 Col3 Col4 Col5 Col6 Col7 Col8 Col9 105 106 107 108 109 110 111 112 113 114 Signed-off-by:

When the client buffer is very small and wraps around a lot, it may well be that a write increases the head such that head == tail. If this happens between the point where a poll is triggered and the actual data is being read, there will be no data to read. This is confusing to applications, which might end up closing the file. This patch solves the problem by making sure the client buffer is never empty after writing to it. Signed-off-by:

Some devices, in particular MT devices, produce a lot of data. This may lead to overflowing of the event queues in evdev driver, which by default are fairly small. Let the drivers hint the average number of events per packet generated by the device, and use that information when computing the buffer size evdev should use for the device. Signed-off-by:

Yannick found that video does not work with 2.6.34. The cause of this bug was that the BIOS had assigned the wrong range to the PCI bridge above the video device. Before 2.6.34 the kernel would have shrunk the size of the bridge window, but since d65245c3 PCI: don't shrink bridge resources the kernel will avoid shrinking BIOS ranges. So zero out the old range if we fail to claim it at boot time; this will cause us to allocate a new range at startup, restoring the 2.6.34 behavior. Fixes regression https://bugzilla.kernel.org/show_bug.cgi?id=16009. Reported-by:

There are devices out there which are PCI Hot-plug controllers with compaq PCI IDs, but are not bridges, hence have pdev->subordinate NULL. But cpqphp expects the pointer to be non-NULL. Add a check to the probe function to avoid oopses like: BUG: unable to handle kernel NULL pointer dereference at 00000050 IP: [<f82e3c41>] cpqhpc_probe+0x951/0x1120 [cpqphp] *pdpt = 0000000033779001 *pde = 0000000000000000 ...

We can often deal with PCI resource issues by moving devices around. In that case, there's no point in alarming the user with messages like these. There are many bug reports where the message itself is the only problem, e.g., https://bugs.launchpad.net/ubuntu/+source/linux/+bug/413419 . Signed-off-by:

The "file" argument for fsync is never null so we can remove this check. What drew my attention here is that 7ea80859: "drop unused dentry argument to ->fsync" introduced an unconditional dereference at the start of the function and that generated a smatch warning. Signed-off-by:

If btrfs_ioctl_snap_destroy() deletes a snapshot but finishes with end_transaction(), the cleaner kthread may come in and drop the root in the same transaction. If that's the case, the root's refs still == 1 in the tree when btrfs_del_root() deletes the item, because commit_fs_roots() hasn't updated it yet (that happens during the commit). This wasn't a problem before only because btrfs_ioctl_snap_destroy() would commit the transaction before dropping the dentry reference, so the dead root wouldn't get queued up until after the fs root item was updated in the btree. Since it is not an error to drop the root reference and the root in the same transaction, just drop the BUG_ON() in btrfs_del_root(). Signed-off-by:

when used Posix File System Test Suite(pjd-fstest) to test btrfs, some cases about setfacl failed when noacl mount option used. I simplified used commands in pjd-fstest, and the following steps can reproduce it. ------------------------ # cd btrfs-part/ # mkdir aaa # setfacl -m m::rw aaa <- successed, but not expected by pjd-fstest. ------------------------ I checked ext3, a warning message occured, like as: setfacl: aaa/: Operation not supported Certainly, it's expected by pjd-fstest. So, i compared acl.c of btrfs and ext3. Based on that, a patch created. Fortunately, it works. Signed-off-by:
