Several drivers contained dummy code to request for memory windows,
even though they never made use of it. Remove all such code

Instead of io_req_t, drivers are now requested to fill out
struct pcmcia_device *p_dev->resource[0,1] for up to two ioport
ranges. After a call to pcmcia_request_io(), the ports found there
are reserved, after calling pcmcia_request_configuration(), they may
be used.

Remove cs_types.h which is no longer needed: Most definitions aren't

All these files use the big kernel lock in a trivial
way to serialize their private file operations,
typically resulting from an earlier semi-automatic
pushdown from VFS.
None of these drivers appears to want to lock against
other code, and they all use the BKL as the top-level
lock in their file operations, meaning that there
is no lock-order inversion problem.
Consequently, we can remove the BKL completely,
replacing it with a per-file mutex in every case.
Using a scripted approach means we can avoid
typos.
file=$1
name=$2
if grep -q lock_kernel ${file} ; then
if grep -q 'include.*linux.mutex.h' ${file} ; then
sed -i '/include.*<linux\/smp_lock.h>/d' ${file}

The CAPI variant of the Gigaset drivers can, in combination with

from the Kconfig option selecting it, and adapt the documentation
accordingly to encourage users to switch to it.

Remove the call to tty_ldisc_flush() from the RESULT_NO_CARRIER
branch of isdn_tty_modem_result(), as already proposed in commit
00409bb045887ec5e7b9e351bc080c38ab6bfd33.
This avoids a "sleeping function called from invalid context" BUG
when the hardware driver calls the statcallb() callback with
command==ISDN_STAT_DHUP in atomic context, which in turn calls
isdn_tty_modem_result(RESULT_NO_CARRIER, ~), and from there,
tty_ldisc_flush() which may sleep.

The Gigaset CAPI driver handled all DATA_B3_REQ messages as if the
Delivery Confirmation flag bit was set, delaying the emission of the
DATA_B3_CONF reply until the data was actually transmitted. Some

behaviour. Change it to actually evaluate the Delivery Confirmation
flag as described the CAPI specification.
