[PATCH] isdn4linux: Siemens Gigaset drivers: code cleanup
With Hansjoerg Lipp <hjlipp@web.de> Source code formatting cleanups for the Siemens Gigaset drivers, such as line length, comments, removal of unused declarations, and typo corrections. It does not introduce any functional changes. Signed-off-by: Hansjoerg Lipp <hjlipp@web.de> Signed-off-by: Tilman Schmidt <tilman@imap.cc> Cc: Karsten Keil <kkeil@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
