Fix incorrect stable backport to bas_gigaset
bas_gigaset: correctly allocate USB interrupt transfer buffer
[ Upstream commit 170ebf85160dd128e1c4206cc197cce7d1424705 ]
This incorrect backport to 2.6.28.10 placed some code into the probe function
which used a pointer before it was initialized. Moving this to the correct
place (as it is in upstream).
