Subject: [161/205] isdn/gigaset: correct CAPI voice connection encoding

2.6.34-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Tilman Schmidt <tilman@...p.cc>

commit 278a582989ade4cb5335762d6c5999562018859d upstream.

Make the Gigaset CAPI driver select L2_VOICE (AT^SBPR=2) as the
layer 2 encoding for transparent connections, like the ISDN4Linux
variant.  L2_BITSYNC (AT^SBPR=0) mutes internal connections and
distorts external ones.

Impact: bugfix
