2015-10-09Revert "USB: qcserial/option: make AT URCs work for Sierra Wireless MC73xx"David Ward
This reverts commit d80c0d14183516f184a5ac88e11008ee4c7d2a2e (excluding the change to MAX_BL_NUM, which has since been removed). The qcserial driver now enables the SET_CONTROL_LINE_STATE request so that AT URCs will work. Move these devices back to the qcserial driver, which is used for other devices in this series that follow the same layout.

2015-10-09USB: qcserial: make AT URCs work for Sierra Wireless devicesDavid Ward
Three Sierra Wireless modems have been found to require the CDC ACM SET_CONTROL_LINE_STATE request on the AT port in order to receive unsolicited response codes, most recently the Dell Wireless 5808e (which is a re-branded Sierra Wireless EM7355). On the other hand, the Sierra Wireless MC7710 does not seem to need this request, but it was found to work either way. Use this request on the AT port of devices with the Sierra Wireless layout in the qcserial driver. The other modems that were moved to the option driver to work around this can now be moved back.

2015-10-09USB: usb_wwan/option: generalize option_send_setup for other driversDavid Ward
Only the option driver implements the send_setup callback; it uses the SET_CONTROL_LINE_STATE request in CDC ACM to generate DTR/RTS signals on the port. This is not driver-specific though and is needed by other drivers, so move the function to the usb_wwan driver (with formatting tweaks), and replace the callback pointer with a flag that enables the request.

This is a partial, context modified revert of commit e463c6dda8f5 ("USB: option: handle send_setup blacklisting at probe"), which introduced an unnecessary struct option_private for storing the interface number used in option_send_setup. Removing this struct will allow option_send_setup to be generalized for other drivers.

2015-10-04usb: Add device quirk for Logitech PTZ camerasVincent Palatin
Add a device quirk for the Logitech PTZ Pro Camera and its sibling the ConferenceCam CC3000e Camera. This fixes the failed camera enumeration on some boot, particularly on machines with fast CPU. Tested by connecting a Logitech PTZ Pro Camera to a machine with a Haswell Core i7-4600U CPU @ 2.10GHz, and doing thousands of reboot cycles while recording the kernel logs and taking camera picture after each boot. Before the patch, more than 7% of the boots show some enumeration transfer failures and in a few of them, the kernel is giving up before actually enumerating the webcam. After the patch, the enumeration has been correct on every reboot.

In big endian cases, macro cpu_to_le16 unfolds to __swab16 which provides special case for constants. In little endian cases, __constant_cpu_to_le16 and cpu_to_le16 expand directly to the same expression. So, replace __constant_cpu_to_le16 with cpu_to_le16 with the goal of getting rid of the definition of __constant_cpu_to_le16 completely.
