2014-07-07of/platform: Fix of_platform_device_destroy iteration of devicesGrant Likely1-23/+9
of_platform_destroy does not work properly, since the tree population test was iterating on all devices having as its parent the given platform device. The check was intended to check whether any other platform or amba devices created by of_platform_populate were still populated, but instead checked for every kind of device. This is wrong, since platform devices typically create a subsystem regular device and set themselves as parents. Instead, go ahead and call the unregister functions for any devices created with of_platform_populate. The driver core will take care of unbinding drivers, and drivers are responsible for getting rid of any child devices that weren't created by of_platform_populate.

For Haswell and Broadwell, if the display power well has been disabled, the display audio controller divider values EM4 M VALUE and EM5 N VALUE will have been lost. The CDCLK frequency is required for reprogramming them to generate 24MHz HD-A link BCLK. So provide a private interface for the audio driver to query CDCLK. This is a stopgap solution until a more generic interface between audio and display drivers has been implemented.

2014-07-03zram: revalidate disk after capacity changeMinchan Kim1-1/+4
Alexander reported mkswap on /dev/zram0 is failed if other process is opening the block device file. Step is as follows, 0. Reset the unused zram device. 1. Use a program that opens /dev/zram0 with O_RDWR and sleeps until killed. 2. While that program sleeps, echo the correct value to /sys/block/zram0/disksize. 3. Verify (e.g. in /proc/partitions) that the disk size is applied correctly. It is. 4. While that program still sleeps, attempt to mkswap /dev/zram0. This fails: mkswap: error: swap area needs to be at least 40 KiB When I investigated, the size get by ioctl(fd, BLKGETSIZE64, xxx) on mkswap to get a size of blockdev was zero although zram0 has right size by 2. The reason is zram didn't revalidate disk after changing capacity so that size of blockdev's inode is not uptodate until all of file is close. This patch should fix the BUG.

2014-07-03md: flush writes before starting a recovery.NeilBrown1-0/+13
When we write to a degraded array which has a bitmap, we make sure the relevant bit in the bitmap remains set when the write completes (so a 're-add' can quickly rebuilt a temporarily-missing device). If, immediately after such a write starts, we incorporate a spare, commence recovery, and skip over the region where the write is happening (because the 'needs recovery' flag isn't set yet), then that write will not get to the new device. Once the recovery finishes the new device will be trusted, but will have incorrect data, leading to possible corruption. We cannot set the 'needs recovery' flag when we start the write as we do not know easily if the write will be "degraded" or not. That depends on details of the particular raid level and particular write request. This patch fixes a corruption issue of long standing and so it suitable for any -stable kernel. It applied correctly to 3.0 at least and will minor editing to earlier kernels.

We need to delete un-finished td from current request's td list at ep_dequeue API, otherwise, this non-user td will be remained at td list before this request is freed. So if we do ep_queue-> ep_dequeue->ep_queue sequence, when the complete interrupt for the second ep_queue comes, we search td list for this request, the first td (added by the first ep_queue) will be handled, and its status is still active, so we will consider the this transfer still not be completed, but in fact, it has completed. It causes the peripheral side considers it never receives current data for this transfer.

2014-06-30usb: musb: dsps: fix the base address for accessing the mode registerLothar Waßmann1-5/+4
commit 943c13971c08 "usb: musb: dsps: implement ->set_mode()" should have made it possible to use the driver with boards that have the USBID pin unconnected. This doesn't actually work, since the driver uses the wrong base address to access the mode register. Furthermore it uses different base addresses in different places to access the same register (phy_utmi).

2014-06-30usb: phy: msm: Do not do runtime pm if the phy is not idleSrinivas Kandagatla1-1/+3
Use case is when the phy is configured in host mode and a usb device is attached to board before bootup. On bootup, with the existing code and runtime pm enabled, the driver would decrement the pm usage count without checking the current state of the phy. This pm usage count decrement would trigger the runtime pm which than would abort the usb enumeration which was in progress. In my case a usb stick gets detected and then immediatly the driver goes to low power mode which is not correct. log: [ 1.631412] msm_hsusb_host 12520000.usb: EHCI Host Controller [ 1.636556] msm_hsusb_host 12520000.usb: new USB bus registered, assigned bus number 1 [ 1.642563] msm_hsusb_host 12520000.usb: irq 220, io mem 0x12520000 [ 1.658197] msm_hsusb_host 12520000.usb: USB 2.0 started, EHCI 1.00 [ 1.659473] hub 1-0:1.0: USB hub found [ 1.663415] hub 1-0:1.0: 1 port detected ...

This patch fixes the intial runtime pm trigger by checking the phy state and decrementing the pm use count only when the phy state is IDLE.

Hence it would report success instead of failure. * of_iio_channel_get_by_name returned a non null pointer if it fails and the callee was expecting NULL to indicate failure. Fixed by returning NULL in the error cases.

2014-06-27iscsi-target: fix iscsit_del_np deadlock on unloadMikulas Patocka1-6/+7
On uniprocessor preemptible kernel, target core deadlocks on unload. The following events happen: * iscsit_del_np is called * it calls send_sig(SIGINT, np->np_thread, 1); * the scheduler switches to the np_thread * the np_thread is woken up, it sees that kthread_should_stop() returns false, so it doesn't terminate * the np_thread clears signals with flush_signals(current); and goes back to sleep in iscsit_accept_np * the scheduler switches back to iscsit_del_np * iscsit_del_np calls kthread_stop(np->np_thread); * the np_thread is waiting in iscsit_accept_np and it doesn't respond to kthread_stop The deadlock could be resolved if the administrator sends SIGINT signal to the np_thread with killall -INT iscsi_np The reproducible deadlock was introduced in commit db6077fd0b7dd41dc6ff18329cec979379071f87, but the thread-stopping code was racy even before. This patch fixes the problem. Using kthread_should_stop to stop the np_thread is unreliable, so we test np_thread_state instead. If np_thread_state equals ISCSI_NP_THREAD_SHUTDOWN, the thread exits.
