* USB: Speedtouch: add pre_reset and post_reset routinesAlan Stern2008-10-22
| | | | | | | | | | | | | | | This patch (as1150) fixes a problem in the speedtch driver. When it resets the modem during probe it will be unbound from the other interfaces it has claimed, because it doesn't define a pre_reset and a post_reset method. The patch defines "do-nothing" methods. This fixes Bugzilla #11767.

* USB: cxacru: Use appropriate logging for errorsSimon Arlott2007-10-12
| | | | | | | | | | | | | | | | When an error occurs, existing logging uses dbg() so the cause of a problem is hard to determine. Error conditions shouldn't only be properly reported with debugging enabled. A side effect of this change is that when an uninitialised device is started, a log message similar to the following is sent: cxacru 5-2:1.0: receive of cm 0x90 failed (-104) This is normal - the device did not respond so firmware will be loaded.

* Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki2007-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

* USB: cxacru: ignore error trying to start ADSL in atm_startSimon Arlott2007-06-08
| | | | | | | | | | | | | | | | | | | | The sysfs adsl_status attribute ignores (aside from returning -EIO to the user) any error sending a START/STOP command to the device and there is at least one firmware which never sends a response but appears to work regardless. Therefore atm_start should also continue if an error is received so that such firmware is usable. The official Conexant driver doesn't expect a reply either but this is for another device (E2 router) and a commonly used firmware does respond. Also, there is no point in changing -ECONNRESET to -ETIMEDOUT since nothing ever checks for either of these values.

* USB: cxacru: create sysfs attributes in atm_start instead of bindSimon Arlott2007-06-08
| | | | | | | | | | | | | | | | | | | | | | Since usbatm doesn't set the usb_interface driver data until after calling bind and heavy_init, it would be NULL when the sysfs attributes are read. Reading the MAC address from atm_dev before atm_dev exists would have been be possible too. Calling create_device_file in atm_start will avoid this problem, and the data is useless until the first status poll runs. However, it must be ready before a status poll does a printk on line status change otherwise userspace could react before the files exist. For completeness I've moved remove_device_file to atm_stop so it's not called in unbind when it's not needed. There's no point starting ADSL if atm_start could still fail either.

* USB: cxacru: ADSL state managementSimon Arlott2007-04-27
| | | | | | | | | | | | | | | | | The device has commands to start/stop the ADSL function, so this adds a sysfs attribute to allow it to be started/stopped/restarted. It also stops polling the device for status when the ADSL function is disabled. There are no problems with sending multiple start or stop commands, even with a fast loop of them the device still works. There is no need to protect the restart process from further user actions while it's waiting for 1.5s.

* usbatm: create sysfs link "device" from atm class device to usb interfaceSimon Arlott2007-04-27
| | | | | | | | | | | | | | | | | | | | | | There is currently no path from the ATM device in /sys to the USB device's interface that the driver is using; this patch creates a "device" symlink. It is then possible to get to the cxacru ADSL statistics (http://lkml.org/lkml/2007/2/23/328): /sys/class/atm/cxacru0/device $ ls *_rate *_margin *_attenuation downstream_attenuation downstream_snr_margin upstream_rate downstream_rate upstream_attenuation upstream_snr_margin If this link is not appropriate I'd have to create device files in /sys/class/atm/cxacru0 instead - which seems less appropriate since the ADSL statistics are for the USB device not ATM (which is running over the ADSL).
