gigaset: remove UNDOCREQ config option
Drop the kernel config option GIGASET_UNDOCREQ, permanently activating the code it controlled, as there have been no reports of problems caused by its activation but many problems caused by it being disabled. Also fix a few bad comments while we're at it. Impact: cleanup Signed-off-by: Tilman Schmidt <> Signed-off-by: David S. Miller <>

-2.6. M105 Undocumented USB Requests
- ------------------------------
- The Gigaset M105 USB data box understands a couple of useful, but
- undocumented USB commands. These requests are not used in normal
- operation (for wireless access to the base), but are needed for access
- to the M105's own configuration mode (registration to the base, baudrate
- and line format settings, device status queries) via the gigacontr
- utility. Their use is controlled by the kernel configuration option
- "Support for undocumented USB requests" (CONFIG_GIGASET_UNDOCREQ). If you
- encounter error code -ENOTTY when trying to use some features of the
- M105, try setting that option to "y" via 'make {x,menu}config' and
- recompiling the driver.
