2011-01-22n_hdlc: fix read and write lockingPaul Fulghum1-45/+45
Fix locking in read and write code of n_hdlc line discipline. 2.6.36 replaced lock_kernel() with tty_lock(). 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.

2011-01-22vt: fix issue when fbcon wants to takeover a second time.Dave Airlie1-2/+7
With framebuffer handover and multiple GPUs, we get into a position where the fbcon unbinds the vesafb framebuffer for GPU 1, but we still have a radeon framebuffer bound from GPU 0, so we don't unregister the console driver. 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. This changes the return value to -EBUSY when the driver is already registered and continues to bind for -EBUSY.

2011-01-22USB: serial: handle Data Carrier Detect changesLibor Pechacek8-40/+50
Alan's commit 335f8514f200e63d689113d29cb7253a5c282967 introduced .carrier_raised function in several drivers. That also means tty_port_block_til_ready can now suspend the process trying to open the serial port when Carrier Detect is low and put it into tty_port.open_wait queue. We need to wake up the process when Carrier Detect goes high and trigger TTY hangup when CD goes low. Some of the devices do not report modem status line changes, or at least we don't understand the status message, so for those we remove .carrier_raised again.

2011-01-22USB: ehci-fsl: Fix 'have_sysif_regs' detectionPeter Tyser3-19/+8
Previously a check was done on an ID register at the base of a CPU's internal USB registers to determine if system interface regsiters were present. The check looked for an ID register that had the format ID[0:5] == ~ID[8:13] as described in the MPC5121 User's Manual to determine if a MPC5121 or MPC83xx/85xx was being used. There are two issues with this method: - The ID register is not defined on the MPC83xx/85xx CPUs, so its unclear what is being checked on them. - Newer CPUs such as the P4080 also don't document the ID register, but do share the same format as the MPC5121. Thus the previous code did not set 'have_sysif_regs' properly which results in the P4080 not properly initializing its USB ports. Using the device tree 'compatible' node is a cleaner way to determine if 'have_sysif_regs' should be set and resolves the USB initialization issue seen on the P4080. Tested on a P4080-based system and compile tested on mpc512x_defconfig with Freescale EHCI driver enabled.

2011-01-22m68k: Uninline strchr()Geert Uytterhoeven1-12/+0
Some versions of gcc replace calls to strstr() with single-character "needle" string parameters by calls to strchr() behind our back. If strchr() is defined as an inline function, this causes linking errors like ERROR: "strchr" [drivers/target/target_core_mod.ko] undefined! As m68k is the only architecture that has an inline strchr() and this inline version is not an optimized asm version, uninline strchr() and use the standard out-of-line C version in lib/string.c instead.

'cs4398_regs' in 'struct xonar_cs43xx' is an array of 'u8' with a size of 8.

The driver assumed it would receive skb packets from MAC80211 which are not cloned. To guard this assumption an assert was placed in the transmit routine. As of kernel 2.6.37 it turns out MAC80211 does pass skb packets that are cloned. The assert is also not needed as it does not lead to a failure state in our driver when the packet is cloned.

2011-01-21can: add driver for Softing cardKurt Van Dijck3-0/+374
This patch adds the driver that creates a platform:softing device from a pcmcia_device Note: the Kconfig indicates a dependency on the softing.ko driver, but this is purely to make configuration intuitive. This driver will work independent, but no CAN network devices appear until softing.ko is loaded too.
