USB: add Zoom Telephonics Model 3095F V.92 USB Mini External modem to cdc-acm

2008-06-09T18:26:58+00:00

commit 6149ed5e3a6207595bd7362af7724d64f44af216 upstream

The patch below is a necessary workaround to support the Zoom Telephonics Model 3095F V.92 USB Mini External modem, which fails to initialise properly during normal probing thus:

May  3 22:53:00 imcfarla kernel: drivers/usb/class/cdc-acm.c: Zero length descriptor references
May  3 22:53:00 imcfarla kernel: cdc_acm: probe of 5-2:1.0 failed with error -22

Adding the patch below causes the probing section to be skipped, and the modem
then initialises correctly.

usblp: Fix a double kfree

2007-10-12T21:55:15+00:00

If submit fails, slab hits a BUG() because of a double kfree.
The today's lesson is, you cannot just slap USB_FREE_BUFFER on code
without adjusting the error paths.

The patch is made bigger by opportunistic refactoring.

usblp: Cosmetics

2007-10-12T21:55:14+00:00

This is a small bunch of cosmetic fixes:
 - Timeout is not a write timeout anymore, rename
 - Condition in poll was confusingly backwards, invert and simplify
 - The comment log gave a wrong impression of version 0.13, terminate it.

usblp: mutex in usblp_check_status

2007-10-12T21:55:14+00:00

Add a mutex to protect the ->statusbuf. Not really an issue, because CUPS
is single-threaded when it talks to the printer, but I feel safer this way.
This should be deadlock-free, but I kept this as a separate patch in case
someone ends running a git bisect.
