| * | | | | | staging: usbip: vhci: give back URBs from in-flight unlink requestsMax Vozeler2011-01-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we never received a RET_UNLINK because the TCP connection broke the pending URBs still need to be unlinked and given back. Previously processes would be stuck trying to kill the URB even after the device was detached.

Previously, only 1GB was being handled by setting the page table size to 4KB, any virtual address beyond of the L1 size used, would fall into memory that does not belong to L1 translation tables, leading to unpredictable results. So, set the L1 table size to cover the entire MMU range (4GB) whether is meant to be used or not.

This change was prompted after an upstream change went into 2.6.37 (netif_tx_stop_queue) that now checks if netif_stop_queue is called before register with netdev is done. This will eliminate the warning message to the log when hv_netvsc driver starts up.

The tty mutex is not dropped automatically when the thread sleeps like the BKL. This results in a blocked read or write holding the tty mutex and stalling operations by other devices that use the tty mutex. A review of n_hdlc read and write code shows: 1. neither BKL or tty mutex are required for correct operation 2. read can block while read data is available if data is posted between availability check and call to interruptible_sleep_on() 3. write does not set process state to TASK_INTERRUPTIBLE on each pass through the processing loop which can cause unneeded scheduling of the thread The unnecessary tty mutex references have been removed. Read changed to use same code as n_tty read for completing reads and blocking. Write corrected to set process state to TASK_INTERRUPTIBLE on each pass through processing loop.

Then when we tried to bind the new radeon framebuffer for GPU1 we never get to the bind call as we fail due to the console being registered already.

The simple fix is to use a temporary variable to store the return value thus preserving the original @m for later use. This is a backport from the commercial Tuxera-NTFS driver and is well tested...

| | * | | | | | | | | ASoC: Fix codec device id format used by some dai_linksLars-Peter Clausen2011-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The id part of an I2C device name is created with the "%d-%04x" format string. So for example for an I2C device which is connected to the adapter with the id 0 and has its address set to 0x1a the id part of the devices name would be "0-001a". Currently some sound board drivers have the id part the codec_name field of their dai_link structures set as if it had been created by a "%d-0x%x" format string. For example "0-0x1a" instead of "0-001a". As a result there is no match between the codec device and the dai_link and no sound card is instantiated. This patch fixes it.
