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 <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>

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.
