This patch (as1315) fixes some bugs in the USB core authorization code: usb_deauthorize_device() should deallocate the device strings instead of leaking them, and it should invoke usb_destroy_configuration() (which does proper reference counting) instead of freeing the config information directly. usb_authorize_device() shouldn't change the device strings until it knows that the authorization will succeed, and it should autosuspend the device at the end (having autoresumed the device at the start). Because the device strings can be changed, the sysfs routines to display the strings must protect the string pointers by locking the device. Signed-off-by:

This patch (as1314) renames usb_configure_device() and usb_configure_device_otg() in the hub driver. Neither name is appropriate because these routines enumerate devices, they don't configure them. That's handled by usb_choose_configuration() and usb_set_configuration(). Signed-off-by:

The USB serial code was a new user of the kfifo API, and it was missed when porting things to the new kfifo API. Please make the write_fifo in place. Here is my patch to fix the regression and full ported version. Signed-off-by:

This fixes LVDS on some mac laptops without a panel edid. v2 - Set proper mode type flags v3 - Note that this is not neceesarily the exact panel mode, but an approximation based on the cvt formula. For these systems we should ideally read the mode info out of the registers or add a mode table, but this works and is much simpler. v4 - Update comments and debug message. Signed-off-by:
