[PATCH 4/9] mISDN: fix sparse warnings

[Hannes Eder <hannes@hanneseder.net>]

Impact: make an exported symbol non static

Fix this warning:

  drivers/isdn/hardware/mISDN/hfcmulti.c:176:1: warning: symbol 'plx_lock' shadows an earlier one
  drivers/isdn/hardware/mISDN/hfcmulti.c:175:19: originally declared here

Note that patch introduces this new warning:

  drivers/isdn/hardware/mISDN/hfcmulti.c:175:12: warning: symbol 'plx_lock' was not declared. Should it be static?

Should 'plx_lock' be declared in a header file?  Or is it really
neccessart to export it?
